chore: get_all_manifests.sh: support tags and make it priority (opend…

…atahub-io#1194)

Jira: https://issues.redhat.com/browse/RHOAIENG-11687

Current script is supposed to be used with branches since it uses
"git clone -b" while preparing tagged releases it is useful to fetch
tags. "git clone -b" can work with tags as well, but if the same
name branch exists it fetches the branch which is not desireable
behaviour if tagged release is being produced.

Try to fetch tag. If it fails fallback to branch.
