Remove 1 warning - DeprecationWarning: pkg_resources is deprecated as an API

Please see diffpy/diffpy.pdfmorph#143

@alisnwu To be added to Phase 2(3.13 python release) milestone

@bobleesj unsure if pkg_resources is still in current diffpy.utils, changelog.rst documented "Remove use of pkg_resources (deprecated)" in v3.2.3

[bobleesj]

@alisnwu you are correct - seeing the error message again: diffpy.utils-3.0.0-py3.7.egg an older version is being installed. I believe this will be fixed once we release 3.5.0. let's close this issue after py313 support.

please close this after sufficient testing that it really is resolved in pdfmorph.
