Remove redundant/wrong Makefile target check-versions

Redundant: Because `uv sync` will do this, and we run that as part of
`make check`.

Wrong: Because Python packages use PEP40 versions anyway, which aren't
always valid semvers, and they normalize semver to PEP40. This means
that by the time you pull the version from `importlib.metadata`, the
version number, which may have started as a valid semver (like
1.0.0-alpha-1) will have been transformed to PEP40 (like 1.0.0a1) and
produce a spurious build break.
