What this PR does / why we need it:

importlib.resources.files
function; it works with the one from the libraryimportlib-resources
.The error
Proposed solution
Using the reference to the module's parent (its package) through spec (docs). We're using
__spec__.parent
as opposed to__package__
because__package__
does not seem to be the way according to this.According to the python-docs, the function should work with both modules and packages, but that does not seem to be the case (link to docs).
