sync-staging.yml

# This action syncs the staging branch to the main branch.
#
# Because we have the staging branch connected to the forestry app,
# we need to update the staging branch with the latest main branch changes
# regularly so that the staging preview is up to date.
# This action will not merge staging with main. It only fast-forwards staging
# to main. This allows for content PRs to staging to remain clean without any
# changes from main.
#
# To use different branches, edit the TARGET_BRANCH bellow or the on trigger branch
