Test failures with pyproject-metadata >= 0.8.0rc1

[mgorny]

I know it's a bit early but Gentoo ended up needing it because of pdm-metadata (sigh). I'll submit a PR to future-proof the test suite. Hope you don't mind.

FWICS it's roughly a mismatch of exception message, and use of comma instead of space in Keywords (apparently the former is correct).

Ah, sorry, now I see there's #612 for it already. My bad.
