Deprecate `use_github_actions()`?

[hadley]

Since it's just a thin wrapper around use_github_action_check_release() with a less informative name. (And that's not a workflow we'd generally recommend anyway, since it only checks on linux)

Or make it do something more useful.

In that case, we might want to deprecate use_github_action_check_release() since it's of relatively limited use, and it always confuses me.

I also don't like that there is only a one-letter difference between this and the much more useful use_github_action()

If we keep the function name and decide to make it more useful, it might be a good candidate for a menu. Sort of like use_version(). Where it takes a look at the project and suggests some actions to configure.
