release-to-wolfi - support updating pipelines only (enterprise, extras) (chainguard-dev#202)

With this you can sync to other dirs also.

$ ./tools/release-to-wolfi vX.Y.Z \
   ~/src/wolfi-os/ ~/src/enterprise-packages ~/src/extra-packages

The big TODO here would be to have github client push and do the PR
also.
