Feature: Auto-import custom sentences from Automations too

[tannisroot]

I have a few custom sentences I've added to Assist through Home Assistant automations, like "Start cleaning" which activates Roomba, or "Good Night" which activates a scene.
While it was not a big deal for me to manually add those sentences to the list of custom ones manually, it's not really great user experience, especially if you are a user with a ton of the custom automation.
But this is just a nit pick in case this gets integrated into mainline home assist, cause my experience with this (flexible_2pass) is SO MUCH better than with whisper, even when using large models!
