Use `NodeJS-bin` instead of the user's `node` install

[Archmonger]

Description

Our test suite currently relies on the user manually installing NodeJS in order for npm commands to be run.

This is an error prone process with way to control what npm version the end-user has. This method also can also fail due to missing PATH variables.

This PR uses premade binaries for npm instead of the user's local npm installation.

FYI @rmorshea

NodeJS-Bin seems pretty nice to me. It's a bit unfortunate the author stopped posting version updates beyond 18.x, but for our purposes 18.x works.
