Run pyroma in tox -e lint instead of pytest

Fixes #9668.
Replaces and closes #9669.

Put pyroma in pre-commit. It can take a few seconds to run, so put it in the manual stage, so it's not run by default.

• A benefit of putting it in pre-commit is it is pinned, so won't suddenly fail when a new version comes out. We also get automated updates.

Run it in tox -e lint, which does the regular pre-commit, and is run on the CI.

Pyroma itself will run check-manifest (when check-manifest is installed), so don't run it twice in tox -e lint or make release-test.
