Upstream 16173 - add force flag to refspec

[cigamit]

When creating a project with allow branch override and then trying to sync it after a rebase & force push, the project update fails with:

fatal: [localhost]: FAILED! => {"changed": false, "cmd": ["/usr/bin/git", "fetch", "--tags", "origin", "refs/heads/*:refs/remotes/origin/*"], "msg": "Failed to download remote objects and refs:  From https://github.com/pb82/ansible-tower-samples\\n ! [rejected]        master     -> origin/master  (non-fast-forward)\\n"}

Adding the force flag + fixes that.

Pull request overview

This PR addresses project update failures after a repository rebase + force-push when the project is configured with branch override enabled, by forcing updates of remote-tracking refs during fetch.

Changes:

• Update the default git refspec used when project.allow_override is enabled to a force refspec (+...) to allow non-fast-forward updates.
