Improve documentation of destination_conf parameter (cloudflare#17631)

* Improve documentation of destination_conf parameter

This commit sheds more light on destination_conf attribute of logpush
job configuration by adding details on the format it has and
stresses more details on accepted schemes such as r2, sumo, etc.

* Improve description of {DATE} placeholder

This commit provides a bit more details on `{DATE}` and restructures
examples.

 As of May 2022, defining a unique destination for a Logpush job will no longer be required. As this constraint has been removed, you can now have more than one job writing to the same destination. 
 :::
 
-* **Cloudflare R2**: bucket path + account ID + R2 access key ID + R2 secret access key; for example: `r2://<BUCKET_PATH>?account-id=<ACCOUNT_ID>&access-key-id=<R2_ACCESS_KEY_ID>&secret-access-key=<R2_SECRET_ACCESS_KEY>`
-* **AWS S3**: bucket + optional directory + region + optional encryption parameter (if required by your policy); for example: `s3://bucket/[dir]?region=<REGION>[&sse=AES256]`
-* **Datadog**: Datadog endpoint URL + Datadog API key + optional parameters; for example: `datadog://<DATADOG_ENDPOINT_URL>?header_DD-API-KEY=<DATADOG_API_KEY>&ddsource=cloudflare&service=<SERVICE>&host=<HOST>&ddtags=<TAGS>`
-* **Google Cloud Storage**: bucket + optional directory; for example: `gs://bucket/[dir]`
-* **Microsoft Azure**: service-level SAS URL with `https` replaced by `azure` + optional directory added before query string; for example: `azure://<BLOB_CONTAINER_PATH>/[dir]?<QUERY_STRING>`
-* **New Relic** New Relic endpoint URL which is `https://log-api.newrelic.com/log/v1` for US or `https://log-api.eu.newrelic.com/log/v1` for EU + a license key + a format; for example: for US `"https://log-api.newrelic.com/log/v1?Api-Key=<NR_LICENSE_KEY>&format=cloudflare"` and for EU `"https://log-api.eu.newrelic.com/log/v1?Api-Key=<NR_LICENSE_KEY>&format=cloudflare"`
-* **Splunk**: Splunk endpoint URL + Splunk channel ID + insecure-skip-verify flag + Splunk sourcetype + Splunk authorization token; for example: `splunk://<SPLUNK_ENDPOINT_URL>?channel=<SPLUNK_CHANNEL_ID>&insecure-skip-verify=<INSECURE_SKIP_VERIFY>&sourcetype=<SOURCE_TYPE>&header_Authorization=<SPLUNK_AUTH_TOKEN>`
-* **Sumo Logic**: HTTP source address URL with `https` replaced by `sumo`; for example: `sumo://<SUMO_ENDPOINT_URL>/receiver/v1/http/<UNIQUE_HTTP_COLLECTOR_CODE>`
-
-For R2, S3, Google Cloud Storage, and Azure, logs can be separated into daily subdirectories by using the special string `{DATE}` in the URL path; for example: `s3://mybucket/logs/{DATE}?region=us-east-1&sse=AES256` or `azure://myblobcontainer/logs/{DATE}?[QueryString]`. It will be substituted with the date in `YYYYMMDD` format, like `20180523`.
+The `destination_conf` parameter must follow this format:
+
+```
+<scheme>://<destination-address>
+```
+
+Supported schemes are listed below, each tailored to specific providers such as
+R2, S3, etc. Additionally, generic use cases like `https` are also covered:
+
+* `r2`,
+* `gs`,
+* `s3`,
+* `cos`,
+* `sumo`,
+* `https`,
+* `azure`,
+* `splunk`,
+* `datadog`.
+
+The `destination-address` should generally be provided by the destination
+provider. However, for certain providers, we require the `destination-address`
+to follow a specific format:
+
+* **Cloudflare R2** (scheme `r2`): bucket path + account ID + R2 access key ID + R2 secret access key; for example: `r2://<BUCKET_PATH>?account-id=<ACCOUNT_ID>&access-key-id=<R2_ACCESS_KEY_ID>&secret-access-key=<R2_SECRET_ACCESS_KEY>`
+* **AWS S3** (scheme `s3`): bucket + optional directory + region + optional encryption parameter (if required by your policy); for example: `s3://bucket/[dir]?region=<REGION>[&sse=AES256]`
+* **Datadog** (scheme `datadog`): Datadog endpoint URL + Datadog API key + optional parameters; for example: `datadog://<DATADOG_ENDPOINT_URL>?header_DD-API-KEY=<DATADOG_API_KEY>&ddsource=cloudflare&service=<SERVICE>&host=<HOST>&ddtags=<TAGS>`
+* **Google Cloud Storage** (scheme `gs`): bucket + optional directory; for example: `gs://bucket/[dir]`
+* **Microsoft Azure** (scheme `azure`): service-level SAS URL with `https` replaced by `azure` + optional directory added before query string; for example: `azure://<BLOB_CONTAINER_PATH>/[dir]?<QUERY_STRING>`
+* **New Relic** (use scheme `https`): New Relic endpoint URL which is `https://log-api.newrelic.com/log/v1` for US or `https://log-api.eu.newrelic.com/log/v1` for EU + a license key + a format; for example: for US `"https://log-api.newrelic.com/log/v1?Api-Key=<NR_LICENSE_KEY>&format=cloudflare"` and for EU `"https://log-api.eu.newrelic.com/log/v1?Api-Key=<NR_LICENSE_KEY>&format=cloudflare"`
+* **Splunk** (scheme `splunk`): Splunk endpoint URL + Splunk channel ID + insecure-skip-verify flag + Splunk sourcetype + Splunk authorization token; for example: `splunk://<SPLUNK_ENDPOINT_URL>?channel=<SPLUNK_CHANNEL_ID>&insecure-skip-verify=<INSECURE_SKIP_VERIFY>&sourcetype=<SOURCE_TYPE>&header_Authorization=<SPLUNK_AUTH_TOKEN>`
+* **Sumo Logic** (scheme `sumo`): HTTP source address URL with `https` replaced by `sumo`; for example: `sumo://<SUMO_ENDPOINT_URL>/receiver/v1/http/<UNIQUE_HTTP_COLLECTOR_CODE>`
+
+For **R2**, **S3**, **Google Cloud Storage**, and **Azure**, you can organize logs into daily subdirectories by including the special placeholder `{DATE}` in the URL path. This placeholder will automatically be replaced with the date in the `YYYYMMDD` format (for example, `20180523`).
+
+For example:
+
+* `s3://mybucket/logs/{DATE}?region=us-east-1&sse=AES256`
+* `azure://myblobcontainer/logs/{DATE}?[QueryString]`
+
+This approach is useful when you want your logs grouped by day.
