Failing tests in CI: Unit `mongod.service` not found.

When investigating a failed deployment of https://github.com/ambanum/OpenTermsArchive/pull/970, I noticed a test fail run on ubuntu-latest. Even when re-running the tests, they still fail.

The relevant logs part is:

sudo systemctl start mongod
Failed to start mongod.service: Unit mongod.service not found.
[…]
Error: Command failed: sudo systemctl start mongod

This happens in every PR now, including some that have no functional change such as https://github.com/ambanum/OpenTermsArchive/pull/971, so this is certainly a broken dependency. Since the MongoDB GitHub Action we rely on has a fixed version, I assume this is an update in the GitHub Actions runners, like in https://github.com/ambanum/OpenTermsArchive/pull/904 😞

See https://github.com/ambanum/OpenTermsArchive/pull/909 for context of using this Action.

Yep, seems related to Ubuntu 22 upgrade: https://github.com/actions/runner-images/issues/6626

Envisioned solutions at this stage of research:

• Check if the dependent action has been updated to implement a fix.
• Implement manual install as in https://github.com/actions/runner-images/issues/6626#issuecomment-1327744126.
• Pin runner version to Ubuntu 20 instead of Ubuntu Latest in CI.

Answer is no. I opened https://github.com/ankane/setup-mongodb/issues/6.
