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.
