Split changelog workflows to separate logic on when each gets run

Hmm, neither of the changelog workflows should be running in this PR as the requirements are not met for either (no changes were made in markdown/ and no changes to the changelog). This used to work before the change in #1388. I thought that if we separated out the validation, then the previous behavior would return. Not sure what I'm missing here.

That was it. Thank you. 😊

Strangely, that was not changed in #1388. Now I'm not sure when that stopped working.
