Add support for making Text-To-Speech send regular text messages instead of notices

When speech-to-text/flow-type = `only_transcribe`, the bot will now send
text messages by default, not notices.

While notice messages may be less desirable with other bots in the room,
it's probably a better default for most people who enable "transcribe-only" mode.

This is an improvement related to https://github.com/etkecc/baibot/issues/14
