[issue44200] Recommend importlib.abc.Traversable users to implement __fspath__

[Filipe Laíns]

New submission from Filipe Laíns <lains at riseup.net>:

The files()/Traversable api is meant to replace ResourceReader api, but it falls short in one dimension, tying the abstraction to a file system path.

I propose to document that Traversable users *should* implement __fspath__ if the Traversable represents a file-system path.

This will essentially make os.fspath(importlib.resources.files(module) / resource) the equivalent of importlib.resources.path(module, resource), for which currently there is no replacement using files().
