New firebase config

[isaabutaa]

Description

Updates the firebase configuration because the previous firebase credentials expired. New credentials come from a new project on Firestore. See the link to the new firestore here. If you can't view the firestore, then try logging in with the google credentials I put in Slack, and then try again.

The files that were updated:

firebase.json

The files that were added to the root directory:

.firebaserc
firestore.indexes.json // this file includes the index we need to query the database
firestore.rules

Testing Steps / QA Criteria

I'm not 100% sure how to test this without merging to the main branch, but if this works, then there should be a preview URL for the app when this PR is created. And if that works, then I think we're okay.

So to test, git checkout new-firebaseConfig, maybe npm install?, then try joining an existing list with this token: hit bale polka. Since this is a new firestore database, we're starting from scratch with the data. You can also try the preview URL and test that.

Thanks for updating the firebase credentials, @isaabutaa. I think it's working. I checked the preview URL and everything is working in the same way. 🎉

Awesome! I'm going to merge it. If it breaks, then I'll revert back to the previous commit
