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

[MattiSG]

When investigating a failed deployment of #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 #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 #904 😞

See #909 for context of using this Action.

Yep, seems related to Ubuntu 22 upgrade: actions/runner-images#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 mongosh, installed by default in ubuntu-20.04, is absent in ubuntu-22.04 actions/runner-images#6626 (comment).
• Pin runner version to Ubuntu 20 instead of Ubuntu Latest in CI.

Answer is no. I opened ankane/setup-mongodb#6.
