Help to add suffix non-release tags only

[gabriel-amyot]

How do I need to configure my action to have this tagging when I commit on any branch but master?
Example:
Previous version is v2.2.1
I create a PR, and every commit in the PR should be tagged like this : v2.2.2-dev.0 , v2.2.2-dev.1, v2.2.2-dev.2
Then when I merge the PR to master, I have would like to have : v2.2.2

I'm almost sure this is possible, since I've seen similar stuff on reported issues, but I can find de correct way to configure the action to even add a suffix.
Thank you
