Update GitHub Actions actions to adapt to Node 16 deprecation

[Piedone]

Describe the bug

GitHub Actions deprecated Node 16 and all actions should migrate to Node 20. Some of the actions we use in our GHA workflows depend on Node 16, so we need to update them.

In most cases, this should just be a matter of referencing the latest versions of the actions we use, e.g. actions/checkout@v4 instead of actions/checkout@v3.

To Reproduce

1. Check out one of our workflow runs.
2. Observe a message similar to the below one under each of these.

Expected behavior

No workflow warnings.

Screenshots

See above.

Do you want to make it part of #15552?

I wouldn't bundle these together, but I can work on this next.
