Add support for Chirp 3 HD sound Google Cloud

[igawa6]

The problem

Hey team, thanks for all the hard work on this! I ran into a small snag where the default Google Cloud tts.speak action always sends along a default pitch value (float 0.0) even when it’s left unset, and the Chirp 3 HD voices don’t support pitch so I’m seeing errors in the logs. I’ve tried every Indonesian voice (for example, id-ID-Chirp3-HD-Aoede) but none seem to work. Could you please take a look? Really appreciate your help!

I'm also not able to use any Chirp 3 HD.
Other voices like Wavenet or Standard are working fine.

In Core logs I see the following error:
