Package Maintenance Github Actions

[zsunberg]

For each package, we should make sure that the the latest version of the following github actions are installed:

• Github actions CI
• TagBot
• CompatHelper

It should be possible to do this with a script, e.g. perhaps with https://github.com/julia-actions/MassInstallAction.jl

There is also: https://github.com/davidanthoff/julia-pkgbutler

Thanks, @lassepe, I already have massinstallaction up and running for now so I'll probably stick to that for this round, but maybe this can help in the future.

Alright, I think this is done, though documenter is probably broken on packages that use it.
