fix(dist): incomplete pth handling

[Caceresenzo]

Add support for comments and non absolute files while reading a .pth file.

Closes #127

Need a bit more time, didn't expected the dist.locate_file(name) to not return a path type.

OK, so the way session_info2._dists.packages_distributions() works, is that it

1. calls importlib.metadata.packages_distributions():

   session-info2/src/session_info2/_dists.py

   Line 20 in 667a104

   pds = dict(pkgs_dists())

2. calls _top_level_editable() to add entries.

So the purpose of the code you’re editing is to find top level packages only in editable distributions (because that’s the part importlib.metadata doesn’t handle).

I assume that .pth file isn’t for an editable distribution, so we should probably just do:

if not path.is_absolute()
    continue

Thanks for taking a look, lets go with that.
