Fix image construction problem

[nutjob4life]

🗒️ Summary

Merge this to fix a problem with building of Docker images.

For details, see build at https://github.com/NASA-PDS/registry-sweepers/actions/runs/7549106501/job/20786456869 … the issue being that the new psutil dependency requires the dev environment at build time.
