migrate to importlib_resources

Replace ugly pkg_resource by importlib_resources

[Davidy22]

I notice current guake repo contains neither importlib_resources nor pkg_resource. Is this still a thing we're doing, or has this been resolved on the side of unrelated other changes in the intervening time?

[gsemet]

close it if no more relevant,

[Davidy22]

Since neither of the packages in question are actually used in the codebase, closing.

Per 31622cb I don't believe pkg_resources was ever used -- but it did used to be imported until recently.

Per bc14194 importlib_metadata is used, but not importlib_resources -- together, these two modules fulfill most of the utility which pkg_resources provides (because pkg_resources does many things, all of them slow, and importlib has been adopting them in a careful and selective manner via carefully scoped APIs).
