Fix leaked Firebase Admin SDK Key... again...

Was in this commit: https://github.com/AutomatingSciencePipeline/Monorepo/blob/989eedd7ada8a44e872b7705c83d46ddeff78832/services/supabase/.env

We already revoked key and generated a new one (it's in the discord)

Attempted to add the .env file to the gitignore, but it did not work because the previous team had already committed their .env files. Deleted the branch that introduced it right away, but that's not enough to fix it, so we regenerated the key as well.

We went through and made a PR that cleans up all old .env files and fixed the other mistakes in the gitignores.

#38 should make this more difficult to cause again
