update.yaml

# This workflow runs nightly and pulls in new version of packit and
# outpack_server into this repository, by running the `scripts/update.py`
# script.
#
# If any updates are found, a pull request is created with the changes. If an
# open pull request already exists, it is updated instead.
#
# In addition to running automatically, this workflow may be triggered
# manually. When doing so, one may specify a particular Git ref to update
# either package to.
#
# Using the `gh` command-line tool, assuming mrc-1234 is a valid branch on the
# mrc-ide/packit repository:
#
# ```
# gh workflow run -R reside-ic/packit-infra update.yaml -f packit=mrc-1234
# ```
