Cannot pass SourceConfig with Includes/Excludes in Reindex call

[kplazinski]

Elastic.Clients.Elasticsearch version: 8.19.X

Elasticsearch version: 8.19.10

.NET runtime version: .net 9

Operating system version: Win11

Description of the problem including expected versus actual behavior:
Hello, in the 8.X verrsion of nuget there is no way to pass Excludes in the call of the reindex api - this code cannot be applied (which works in the nuget 9.X), because SourceFields cannot accept new instance of the SourceConfig class.

await _client.ReindexAsync(x => x.Source(src => src.SourceFields(new Elastic.Clients.Elasticsearch.Core.Search.SourceConfig(new SourceFilter { Excludes = Fields.FromString("something") }))));

Hi @kplazinski ,

there was a bug in the specification that got fixed in this PR. However, we did not backport this change to the 8.19 branch - presumably because it's a breaking change.

I'll clarify internally if it would be acceptable to backport this. Otherwise I'm fine with manually fixing it for the .NET client.
