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

+The following configuration values are recognized:

+- (default) `text`: the transcribed text is sent as a regular message. This is more convenient if you'd like to forward the transcribed message to other rooms.
+
+- `notice`: the transcribed text is sent as a notice message. This provides better compatibility with other bots in the room, as they are less likely to interact with messages of type notice.
