Incompatible with Python 3.12

Upgrading my project to Python 3.12 runs into the following error:

   from pyramid_celery import celery_app

E   AttributeError: module 'configparser' has no attribute 'SafeConfigParser'. Did you mean: 'RawConfigParser'?

It seems there was an attempt to address this in a PR created last year: #94.

Is this package still maintained?
