chore: add release-plz workflow (#140)

* chore: add release-plz workflow

This removes the need for the custom crates publishing, and the tag
should trigger the npm and pypi.

* fix: update lockfile

* chore: remove locked check

* ci: remove rust cache

We were running out of disk space while building?

* fix: re-add the cache

* chore: free up disk space
