user_project_ci action fails in the "Commit" stage (when protected branches are enabled)

[rolfmobile99]

If someone has set up protected branches for their GitHub account (perfectly reasonable to do),
then the user_project_ci action will fail!
This is because it does a "git push" and expects that to work.

The specific error message looks something like:
GH006: Protected branch update failed for refs ...

The workaround is to turn off the protected branch.
(a bit hard to find on github.. look under Settings/Branches then "Branch protection rule")
