* Update description of release process to include options for next RCs

Often we excluded individual providers from release and we have two
options how to handle them - either release them on their own with
an accelerated vote, or include the providers in the next wave of
providers.

This PR improves description of our process and email template to
explain it better and guide the release manager on what to do.

Also improved notification message
