pull_request_target:
# This workflow depends on the base branch of the PR,
# but changing the base branch is not included in the default trigger events,
# which would be `opened`, `synchronize` or `reopened`.
# Instead it causes an `edited` event, so we need to add it explicitly here
# While `edited` is also triggered when the PR title/body is changed,
# this PR action is fairly quick, and PR's don't get edited that often,
# so it shouldn't be a problem
