include the title tag in the message

[mll0]

Feature Request

I'd like to include my brand new Signal connection (thanks for the great plugin btw) in a notify group.

Now, when I run:

action: notify.emergencies_group
data:
  message: test emergency 1
  title: test title

the "test title" doesn't get passed to the Signal message, which is a pity, as the title itself can contain important info. A nice change would be to let it go through, as the first line, into the message. For instance, that's Telegram's plugin behaviour.
