fix setup tools deprecation pkg_resource warning manging Jedi/Emacs communication

[plandes]

After installing Python 11 and installing the latest setup tools, Emacs JEDI stopped working because a warning message mangled the JEDI/Emacs communication.

The setuptools under version 69.0.2 has deprecated the pkg_resources module and produces this warning when loading jediepcserver.py:

DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html

This pull request simply adds a warning ignore to suppress it matching on the category and error message. Per the URL given, it will need to be replaced with importlib at some point, but this at least this fixes it for the short term.

The maintainer of jedi responded and mentioned the aforementioned sys_path was taken out and replaced with the jedi.Project API instead in this issue.

Would creating a pull request that makes these changes be helpful?

Thanks in advance
