Fire issue events on HA's bus

[mdegat01]

Proposed change

Follow up to #3818 - the events need to be on HA's bus, not supervisor's. HA isn't listening to supervisor's event bus, supervisor fires events of type supervisor/event when HA needs to know about it.

• Dependency upgrade

Let's add a message for humans and not only an err

@pvizeli Changed both places (async_supervisor_event and async_supervisor_update_event) to this:

_LOGGER.error("Could not send message to Home Assistant due to %s", err)

Sound good?

There is no need for exception handling in both those, one of them should call the other

Right that's true. I'll adjust it in a follow-up
