docs(clickpipes): Add new regions and clarify IP whitelisting logic

This commit adds new ClickPipes deployment regions (`ap-south-1`, `ap-southeast-2`, `us-west-2`) and updates the static IP address list.

The documentation is restructured to clarify the IP whitelisting requirements based on the service's creation date:
- Services in the new regions created on or after June 24/25, 2025, should use the new region-specific IPs.
- Older services in these regions must continue using the `us-east-1` IPs.
- The fallback logic for other regions is also clarified.

 ## List of Static IPs {#list-of-static-ips}
 
-The following are the static NAT IPs (separated by region) that ClickPipes uses to connect to your external services.
-Add your related instance region IPs to your IP allow list to allow traffic.
-If your instance region is not listed here, it will fall to the default region:
-
-- **eu-central-1** for EU regions
-- **us-east-1** for instances in `us-east-1`
-- **us-east-2** for other all regions

+
+For services created in `ap-south-1`, `ap-southeast-2`, and `us-west-2` **on or after 24 Jun 2025**, ClickPipes will be deployed in the same region, and you should use the region-specific IPs from the table below. For services created in these regions **before** this date, please use the IPs for `us-east-1`.
+
+For all other services, ClickPipes traffic will originate from a default region based on your service's location:
+- **eu-central-1**: For all services in EU regions.
+- **us-east-1**: For all services in `us-east-1`.
+- **us-east-2**: For all other regions not explicitly listed.

 ## Adjusting ClickHouse settings {#adjusting-clickhouse-settings}
 ClickHouse Cloud provides sensible defaults for most of the use cases. However, if you need to adjust some ClickHouse settings for the ClickPipes destination tables, a dedicated role for ClickPipes is the most flexible solution.
