[release/8.0] Update HttpClientJsonExtensions.Get.AsyncEnumerable.cs

[github-actions]

Backport of #92180 to release/8.0

/cc @eiriktsarpalis @WeihanLi

Customer Impact

We received a customer reported issue that one of the newly added IAsyncEnumerable methods in the System.Net.Http.Json library is not using the correct default settings when deserializing values.

For instance, even though all other methods in the library use camelCase conversion, the impacted new methods do not.

Testing

Added unit testing covering the impacted scenario.

Risk

Low. Makes a minor change in product code making it consistent with other components in the same library (including other IAsyncEnumerable methods added in the same change).

Hi @eiriktsarpalis , just to mention, this also fixes the bug when trying to use a custom serializer option

sample code to reproduce

using var httpClient = new HttpClient();
httpClient.BaseAddress = new Uri("http://localhost:5297");
var stream = httpClient.GetFromJsonAsAsyncEnumerable<Job>("api/Jobs", 
    new JsonSerializerOptions(JsonSerializerDefaults.Web)
);

Exception likes below:

System.InvalidOperationException: JsonSerializerOptions instance must specify a TypeInfoResolver setting before being marked as read-only.
   at System.Text.Json.ThrowHelper.ThrowInvalidOperationException_JsonSerializerOptionsNoTypeInfoResolverSpecified()
   at System.Text.Json.JsonSerializerOptions.MakeReadOnly()
   at System.Net.Http.Json.HttpClientJsonExtensions.FromJsonStreamAsyncCore[TValue](HttpClient client, Uri requestUri, JsonSerializerOptions options, CancellationToken cancellationToken)

This has my support for RC2, @artl93. It's a broken/imcomplete 8.0 scenario reported by a customer.
