google_cloud tts: 'Journey' voice type is unusable

The problem

While experimenting with some of the newer voice types available via Google Cloud TTS, I noticed that the 'Journey' family of voices is not usable from HomeAssistant.

Neither the 'Studio' nor 'Journey' voices currently support the pitch parameter, but the 'Journey' voices will throw an error if the speaking_rate or pitch fields exist in the API request at all (even with neutral values of 1.0/0.0, respectively):

2024-11-17 16:19:39.598 ERROR (MainThread) [homeassistant.components.google_cloud.tts] Error occurred during Google Cloud TTS call: 400 This voice does not support speaking rate or pitch parameters at this time.

Perhaps the easiest solution would be to avoid specifying the speaking_rate/pitch fields when generating the AudioConfig unless they differ from the default?
