Why?
firebase-tools is a CLI tool for all Firebase projects, regardless of language. To date, the methods for installation have been downloading the CLI from the Firebase website or through npm, with npm being the primary method advertised.
With asdf and the asdf-firebase plugin, users/teams of any Firebase project can install and pin the version of the Firebase CLI without needing to manage Node.js or npm!

Why are there Node deps here?
I decided the value of commitlint & sharing Git Hooks with husky were greater than the cost of including these deps. Not only this, but dogfooding asdf for dev deps makes this less of an issue.
