ENG-87042: clarify TTS language parameter supports lowercase locales

[rishabh-bhargava]

Summary

• Relaxes the TTS language enum to a free-form string so locale codes (e.g. zh-hk) are accepted.
• Updates the description to document that locales are supported and must be lowercase (e.g. zh-hk for Cantonese, not zh-HK).
• Mirrors mintlify-docs#764 which made the same change in the docs source.

Context

User reported zh-HK was failing for Cantonese on English_Aussie_Bloke (Minimax); lowercase zh-hk works. Linear: ENG-87042.

Test plan

• Spec lints / renders correctly in downstream docs sync.
• No clients depended on the previous enum constraint for validation.
