Fixed #312, simplify firebase deploy

[rhelmer]

There's really no need to push to a git branch, we can just store an archive of the deployable version of the site:

• the firebase config
• the compiled functions
• the compiled website

This works similar to before but without involving git:

1. check out and build the site in production mode
2. persist the workspace (next step modifies things)
3. test the site (reconfigures to dev mode for this)
4. restore the workspace from step (2)
5. zip up and archive the workspace
6. if this is master branch, run firebase deploy

This is going to be a little tricky to test before landing, I'll need to use some temporary commits to make it deploy from a this test branch, then I will rebase those away.

I'd like to continue looking at alternatives such as GitHub actions, but this feels like a relatively small change that should make our deployments more solid.

Note that I tried setting the filter to use this branch instead of master and it gets all the way to the final deploy step but it looks like the service account is missing a permission, I alerted SRE:

#!/bin/bash -eo pipefail
GOOGLE_APPLICATION_CREDENTIALS="$HOME"/gcloud.json ./node_modules/.bin/firebase deploy --project $PROJECT_ID_STAGE
