resourceutil: use `from importlib import resources` Without this patch, we get the following error from when trying to run hg with PyOxidizer: module 'importlib' has no attribute 'resources' I don't know what why that happens, but `from importlib import resources` is the form I would prefer anyway, so let's use that now that the impoort-checker has been fixed.

import-checker: allow all absolute imports of stdlib modules Before this patch, we didn't allow imports like from importlib import resources (That's the reason I used `import importlib.resources` in D7629.) I think that form is still an absolute import, so I don't think we forbade on purpose. Differential Revision: https://phab.mercurial-scm.org/D7700
