Pull request overview

This PR updates azure-ai-translation-text for the v2 GA release, including moving to the stable Translator API version and aligning the package surface area (models, enums, client initialization, and test recordings) with the GA contract.

Changes:

• Promote the package to 2.0.0 GA and switch defaults to api-version 2026-06-06.
• Update the public model surface (remove grade, add TranslationTone / TranslationGender enums and types).
• Simplify client construction/auth plumbing and adjust tests/recording matching to be resilient across api-version changes.

_is_array_encoded_deserializer appears to never match the deserializer produced by get_deserializer for array-encoded strings. get_deserializer returns functools.partial(_deserialize_array_encoded, <delimiter>) (whose first arg is a str), but _is_array_encoded_deserializer checks that deserializer.args[0] is itself a functools.partial, so the encoded-string path in _deserialize_sequence won’t trigger and string inputs may be incorrectly treated as iterables. Consider changing the detection to check getattr(deserializer, "func", None) is _deserialize_array_encoded (and likewise for the union case).
