Add GitHub Actions to test build and parsing pipelines

[ovflowd]

We want to add a GitHub Actions pipeline that triggers on a new commit on main of nodejs/node to:

• Retrieve the repo contents at the time of the commit (git checkout or fetch or whatever) (our goal are the API docs)
• Runs the CLI for the API Doc Tooling giving the input glob and output directory
• Generates the MDX as an output target to begin with
• Verifies that all files were generated
• Produces an artifact with a zip of the generated files?

I don't really understand this issue, the goal is to fetch the doc (which is on the nodejs/node repo) into this repo to generate an artifact output.
