Drop pep440 dependency

[LecrisUT]

Just a random drive-by PR. Noticed from python-pep440 being orphaned on Fedora that there are some packages that still require it, this being one of them. In principle packaging should be used instead of all of these kind of projects moving forward.

In this case it is likely that this is not needed at all and hatch-nodejs-version would take care of it automatically, but I did not confirm it, so I've left the test as-is for now.
