## description
this PR
- adds an empty `tests/mod.nu` module so that `nupm test` can work
- adds a CI greatly inspired by https://github.com/nushell/nupm/pull/30
  - does not need the `CWD` trick for Windows (:pray:)
  - pulls down Nushell from nightly builds
  - clones Nupm
  - shows the version of Nushell
  - runs the tests
