pyproject: use micropython-uncrustify

This switches to using micropython-uncrustify instead of the distro
package. Upstream uncrustify made breaking changes, so we need a way
to use an exact version, which is provided by micropython-uncrustify.

Also move black to the new lint group, since it is a linter and update
the github action accordingly.
