Feature request: check calls to package managers to validate list of packages user is attempting to install

[cooljeanius]

A lot of my time debugging GitHub Actions is spent trying to track down the proper spellings for package names passed to commands like sudo apt-get install. It would be nice if actionlint could check lists of packages like these for me so that I don't have to do the whole "commit and then check the CI failures log" cycle. Note that I can't just check with my own local copy of apt-get because I use a Mac, and my apt-get binary comes from Fink, which comes with a different package distribution list from the ones available on the the Ubuntu runners that GitHub Actions uses.
