Add support firebase-admin 12 in peerDependencies

[mcfarljw]

https://github.com/firebase/firebase-admin-node has been updated to v12 and is not a version included in the current peerDependencies.

"firebase-admin": "^8.0.0 || ^9.0.0 || ^10.0.0 || ^11.0.0 || ^12.0.0",

Related to firebase/firebase-functions#1496.

I have the same issue when trying to use the latest version of firebase-admin with firebase-functions.

Hey @taeold when you have a chance could you please look into this or let us know who we should reach out to? We cannot update firebase-admin to 12.0.0 until we get an update for firebase-functions-test.

Also, just want to check if this lib is still supported? I noticed that there hasn't been any activity in the last 9 months.

Thanks!

Same here - I see the firebase-functions was just updated to support v12 of firebase-admin, but because the function tests haven't been updated deployments are blocked.

It looks like this was just fixed in 3.1.1
