Python 3.12 versioneer help

[sef43]

Hello MDA devs!,

I have just noticed that the CI on my repo for the MDAKit openmm-mdanalysis-reporter is failing with python 3.12: https://github.com/sef43/openmm-mdanalysis-reporter/actions/runs/7367470282

It is based on the cookie-cutter template. The error is coming from the versioneer script:

Processing /home/runner/work/openmm-mdanalysis-reporter/openmm-mdanalysis-reporter
  Installing build dependencies: started
  Installing build dependencies: finished with status 'done'
  Getting requirements to build wheel: started
  Getting requirements to build wheel: finished with status 'error'
  error: subprocess-exited-with-error

  × Getting requirements to build wheel did not run successfully.

I guess something needs updating?
Hopefully you have seen this before and know what I need to change, thanks!

@sef43 sorry to see this has affected you too - it's primarily an issue with versioneer being out of date. This unfortunately happens because we've been using versioneer in vendored mode so it doesn't update as things change. We've been slowly migrating everything on our end to use versioningit instead, which is less prone to these issues.

I've opened a quick PR on your repo to demonstrate what the changes would look like: https://github.com/sef43/openmm-mdanalysis-reporter/pull/3

Closing as fixed in the kit.

Thanks @IAlibay !
