[JENKINS-30016] Git Duplicate build for every workspace

Enable: Execute concurrent builds if necessary

Branch specifier *

Enable: Build when a change is pushed to GitHub

Enable: Prune stale remote-tracking branches

I have 6 executors.

Every branch will then be built one times on each workspace. That is 6 times in total for every commit

Duplicate builds say:

"""

No changes.

Started by an SCM change (or Started by Github push by someone)

"""
