Add keywords to the default sync overload

For sync callers who use the new keywords hint with the default JSON transcription path, overload resolution has to match this first create overload, but it only added languages and still lacks the new keywords parameter that the implementation serializes below. Typed users calling client.audio.transcriptions.create(file=..., model="gpt-transcribe", keywords=[...]) now get a false “no overload matches” error unless they pass an otherwise unnecessary stream=False/alternate response format, so mirror the async/default overload here.

Useful? React with 👍 / 👎.

[HAYDEN-OAI]

Reviewed the SDK-134 transcription-model launch, verified the corrected synchronous transcription overload, and confirmed all required release and compatibility checks pass.
