Add firebase-tools to npmjs.com/provider.yml

As mentioned here.

note that this doesn’t work great RN. It will be suggested for command-not-found, but typing x doesn't run it.

It does work pkgx firebase foo, but that's it.

If you want firebase to be a tool that can be added to environments, it needs to be fully packaged. For node packages this is quite easy, there's a few examples in the pantry you can riff off.

Longer term I would like to make “providers” more proper, but I haven't had the ideas about that yet. I will at least fix the x bug.

Thanks, I will work on that!
