Replace deprecated pkg_resources with stdlib #239

pkg_resources has been deprecated by setuptools for quite a while: https://setuptools.pypa.io/en/latest/pkg_resources.html

It's got some bugs/warts:

So switch to using importlib functions which are part of the Python standard library as of 3.8.

This is less error-prone, and also removes the need for setuptools to be installed in order for this panel to work.

I realize we technically still support 3.7, but I thought it was fine to change this particular panel to require 3.8, as 3.7 support is best effort given that it's now EOL'd by the core Python team.

I also removed the relative path location for specific libraries as it was simply blank for me on Python 3.12... I think showing the location of the site packages directory should suffice. If someone later wants to build this out further, they're more than welcome to.

Note that importlib.metadata.distributions() does have an outstanding issue that it reports a local editable install twice, but they plan to eventually fix that:

I started down this rabbit hole because I opened the Versions panel on 3.12 and it was blank saying "you need to install setuptools", which smelled wrong...

I don't think it's worth forcing the setuptools requirement for newer Pythons just so that this panel can work for Python 3.7.

`pkg_resources` has been deprecated by `setuptools` for quite a while:
https://setuptools.pypa.io/en/latest/pkg_resources.html

It's got some bugs/warts:

* pypa/setuptools#2531
* https://discuss.python.org/t/will-setuptools-remove-pkg-resource-module-in-the-future/27182

So switch to using `importlib` functions which are part of the Python
standard library as of `3.8`.

This is less error-prone, and also removes the need for `setuptools` to
be installed in order for this panel to work.

I realize we technically still support `3.7`, but I thought it was fine
to change this particular panel to require `3.8`, as `3.7` support is
best effort given that it's now EOL'd by the core Python team.

was simply blank for me on Python 3.12... I think showing the location
