ci(docs-infra): fix deployment to Firebase (#26746)

Previously, `firebase-tools@3.x` was used and the deployment from
CircleCI failed with `Unexpected error` (HTTP code: 410).

This commit ensures that we use a recent version of `firebase-tools` for
deploying to Firebase. It also ensures that we use the locally installed
`firebase-tools` (not sure where it came from before 😁).
