Update from Template #67

name: Update from Template
# This workflow keeps the repo up to date with changes from the template repo (REMOTE_URL)
# It duplicates the REMOTE_BRANCH (into UPDATE_BRANCH) and tries to merge it into the
# this repos default branch (which is checked out here)
# Note that this requires a PAT (Personal Access Token) - at best from a servicing account
# Also note that you should have at least once merged the template repo into the current repo manually
# otherwise a "refusing to merge unrelated histories" error might occur.
