edk2_invocable: Fix pkg_resources deprecation warning (#985)

The following warning is now present (with Python 3.12.10):

```
/opt/hostedtoolcache/Python/3.12.10/x64/lib/python3.12/site-packages
  edk2toolext/edk2_invocable.py:31:
    UserWarning: pkg_resources is deprecated as an API.
	See https://setuptools.pypa.io/en/latest/pkg_resources.html.
	The pkg_resources package is slated for removal as early as 2025-11-30.
	    Refrain from using this package or pin to Setuptools<81.

  import pkg_resources
```

This change replaces it with `importlib`.
