Identifying multiple languages is not supported in Python SDK (different from JavaScript or Java SDK)

[victoryingliwang]

Unlike JavaScript or Java AWS Transcribe SDKs, parameters "identify_multiple_languages" and "language_options" are not supported in TranscribeStreamingClient.start_stream_transcription in the python SDK.

By comparison, I am able to find the multiple languages support in the SDKs for JavaScript and Java:

JavaScript client SDK (link: https://github.com/aws/aws-sdk-js-v3/blob/main/clients/client-transcribe-streaming/src/models/models_0.ts):
StartStreamTranscriptionRequest:
IdentifyMultipleLanguages?: boolean | undefined;
LanguageOptions?: string | undefined;

Java client SDK (link: https://github.com/aws/aws-sdk-java-v2/blob/master/services/transcribestreaming/src/main/resources/codegen-resources/service-2.json):
StartStreamTranscriptionRequest:
LanguageOptions,
IdentifyMultipleLanguages
