cosmos: Changelog prep for 0.28 release (#3116)

This PR preps the CHANGELOG.md for the 0.28 release. There are three
separate changes here, which I put in separate commits, because the
overall diff is a little busier than you might expect :).

1. Added a missing changelog entry for #2969. I forgot to ensure that
was added before merging, so I put it in here.
2. Replaced our usage of `*` in the changelog with `-` so we're
consistent with other SDKs, and consistent within the file (since a
recent Core change added a changelog entry using `-`)
3. Marked the changelog entry for `0.28.0` as releasing tomorrow.

 # Release History
 
-## 0.28.0 (Unreleased)
+## 0.28.0 (2025-10-07)
 
 ### Features Added
 
-* Added `Query::with_text()` and `Query::append_text()` methods to modify query text after creation ([#3044](https://github.com/Azure/azure-sdk-for-rust/pull/3044))
+- Added `Query::with_text()` and `Query::append_text()` methods to modify query text after creation ([#3044](https://github.com/Azure/azure-sdk-for-rust/pull/3044))
+- Added `PatchDocument::with_condition()` methods to allow setting a condition on a patch operation ([#2969](https://github.com/Azure/azure-sdk-for-rust/pull/2969))
 
 ### Breaking Changes
 
 - Client methods that return a `Response<T>>` asynchronously buffer the entire model within the internal pipeline, so `into_body()` and other methods on the response are no longer async.

 ## 0.24.0 (2025-06-10)
 
 ### Features Added
 
-* Added a function `CosmosClient::with_connection_string` to enable `CosmosClient` creation via connection string. ([#2641](https://github.com/Azure/azure-sdk-for-rust/pull/2641))
-* Added support for executing limited cross-partition queries through the Gateway. See <https://learn.microsoft.com/rest/api/cosmos-db/querying-cosmosdb-resources-using-the-rest-api#queries-that-cannot-be-served-by-gateway> for more details on these limitations. ([#2577](https://github.com/Azure/azure-sdk-for-rust/pull/2577))
-* Added a preview feature (behind `preview_query_engine` feature flag) to allow the Rust SDK to integrate with an external query engine for performing cross-partition queries. ([#2577](https://github.com/Azure/azure-sdk-for-rust/pull/2577))

 ### Breaking Changes
 
-* `FeedPager<T>` now asynchronously iterates items of type `T` instead of pages containing items of type `T`. Call `FeedPager::into_pages()` to get a `PageIterator` to asynchronously iterate over all pages. ([#2665](https://github.com/Azure/azure-sdk-for-rust/pull/2665))

 ## 0.23.0 (2025-05-06)
 
 ### Features Added
 
-* Decoupled query responses from HTTP to allow for handling non-HTTP transports for queries. ([#2393](https://github.com/Azure/azure-sdk-for-rust/pull/2393))
+- Decoupled query responses from HTTP to allow for handling non-HTTP transports for queries. ([#2393](https://github.com/Azure/azure-sdk-for-rust/pull/2393))
 
 ### Breaking Changes
 
-* Query APIs (`CosmosClient::query_databases`, `DatabaseClient::query_containers`, `ContainerClient::query_items`) now return a `FeedPager` instead of an `azure_core::Pager`. The `FeedPager` type provides an abstraction over the transport layer, allowing for more flexibility when queries are executed over non-HTTP transports or are decoupled from specific HTTP responses (such as in cross-partition queries).
