CI: deprecate $(AUTORELEASE) via comments

CI: deprecate $(AUTORELEASE) via comments

Autorelease causes some issues like heavy bandwidth usage as well as
non-deterministic package releases whenever someone doesn't use the full
git log.

With this comment all modified packages are checked and if they use
the autorelease feature, kindly comment to the user to change that.
