* Update Microsoft TTS supported languages
`script.microsoft_tts` scrapes Microsoft Azure documentation for
the list of supported languages and saves them to
`homeassistant.generated.microsoft_tts` for use in the component.
This adds support for more TTS languages, like fa-ir (Persian).
* Improve xpath query for Microsoft TTS languages
* Remove asserts for Microsoft TTS languages
* Add more tests for Microsoft TTS languages
