ceph-backport.sh: add deprecation warning

The script is not maintained in the stable versions of Ceph.

This commit is not a cherry-pick from master, because the script is maintained
in master. It is unmaintained only in the stable versions, like
"octopus".

Fixes: https://tracker.ceph.com/issues/42194
