Here path and url names are identical but don't match package name. This passes here but is detected by #1114

I should maybe have kept this as draft as the d.p.o discussion and pypa/packaging.python.org#2018 are going in a different direction.

@henryiii I see you changed the title to fix(pylock), but it is not really a fix, it's rather a new validation check.

[sbidoul]

So I suggest reverting this one. I'll prepare another PR when pypa/packaging.python.org#2018 is merged.

The prefix there is to indicate where in the changelog the change should go. I'll probably merge all the pylock related things, so feat might be okay. I'd consider it more of a fix, though. fix is a modification to behavior, rather than new behavior. There's also chore, ci, refactor, perf, and docs.
