Publish a GHA that runs `bluehawk copy`

[nlarew]

The goal here is to automate Bluehawk "artifacts" via CI/CD in a reusable way.

Currently the MongoDB docs team uses a locally-defined push-to-artifact-repo action that calls bluehawk-plugin-git.

Ideally the bluehawk copy GHA wouldn't be so tightly coupled to Git output. We should enable pluggable output targets (e.g. GitHub & S3) and/or ensure that there's clean way to pipe a copied file/directory within GHA to another step/job that handles it separately.
