Continuously generating internationalization `.pot` files

## Enhancement proposal
Currently, `.pot` files are not automatically updated when docstrings change, meaning they have to be manually regenerated regularly. This is not ideal, as translators may be translating old docstrings, wasting their time and effort. It would be great if they could be automatically regenerated when docstrings change, perhaps by including the process in our pre-commit ci.

## Additional comments

Start by locating the existing `.pot` files and the process that generates them, then inspect the pre-commit CI configuration. Determine how docstring changes can trigger regeneration and verify that the generated translation templates stay current after a docstring change.
