While we are now testing with python 3.13, I am now working on trying to get the tests to pass. 

An issue that I've run into is that there is a dependency (stregion) that has the python version pinned to less than python 3.13.  It looks like it was originally pinned because things were failing. 

While the tests appear to work locally, both on linux and mac. The tests fail for the python 3.13 test. When we do another test with all the dependencies forced to most recent version (devdep), the tests result in a c compilation issue (cdriz) which doesn't seem to make sense. We suspect that there is a (uv) installation issue that is not being raised in the logs. 

I've submitted a PR to remove the stregion pin, and will continue trying to diagnose the issue.

There are now two PR out for testing with python 3.13. We now have the github action tests that we run on drizzlepac as well as the new regression testing suit. We may be able to get rid of the drizzlepac tests, but for the meantime, I have updated the github action files for both. 

Code for completing this task is in Drizzlepac PR #⁠1936 and spacetelescope/regressiontest PR #⁠191.

Another ticket will be created to get the tests to pass.
