Wolfgang Walther 65315e5400 workflows: self-test on change
All workflows where it's remotely useful now trigger on a pull_request
event when the workflow file itself is changed. This gives us basic
sanity testing of changes to workflow files itself and reduces the need
for manual tests in forks.

# This workflow depends on two GitHub Apps with the following permissions:
# - For checking code owners:
# - Permissions:
# - Repository > Administration: read-only
# - Organization > Members: read-only
# - Install App on this repository, setting these variables:
# - OWNER_RO_APP_ID (variable)
# - OWNER_RO_APP_PRIVATE_KEY (secret)
# - For requesting code owners:
# - Permissions:
# - Repository > Administration: read-only
# - Organization > Members: read-only
# - Repository > Pull Requests: read-write
# - Install App on this repository, setting these variables:
# - OWNER_APP_ID (variable)
# - OWNER_APP_PRIVATE_KEY (secret)
#
# This split is done because checking code owners requires handling untrusted PR input,
# while requesting code owners requires PR write access, and those shouldn't be mixed.
#
# Note that the latter is also used for ./eval.yml requesting reviewers.
