Remove types-click from Nox session for mypy (#952)

* Remove types-click from Nox session for mypy

click >= 8.0 ships with py.typed, so types-click is not required.

Installing types-click with click >= 8.0 leads to a mypy error:

- python/typeshed#5642

* Remove unused `type: ignore` on `@click.version_option`
