chore: Switch to `netlify-cli`

[rschristian]

I don't really intend to merge this but wanted to have it in case we are forced to switch off netlify-lambda (which has been deprecated and relies on Webpack 4, which has issues past Node 17).

netlify-cli is absurdly large (as you can tell by the diff), adds ~1300 deps and increases node_modules from 481M to 784M. IMO, this is a complete non-starter. Almost certainly better off going with a custom build/serve set up.
