Ensure artifacts are only uploaded in safe situations

This commit:

Turns on uploading of artifacts again but only if CLI version is
>= 2.20.3. I implemented the check using our feature flag functionality.
I was on the fence about this since it makes the PR more complex.
However, it does give us more flexibility when controlling artifact
uploads.

Also, I renamed the two workflows that were previously disabled. This
way we will not accidentally enable the old workflows for previous
versions of the action.
