@diegoarceof PR looks great! Could you also add deployment to this? See:

• https://github.com/hal9ai/hal9/blob/main/.github/workflows/apps-devel.yaml
• https://github.com/hal9ai/hal9/blob/main/.github/workflows/apps-prod.yaml

In addition, could we split those files to only deploy when each app changes? You'll have to break it down into multiple files, I believe:

on:
  push:
    branches:
      - release
    paths:
      - .github/workflows/apps*
      - apps/**

would change to something like:

on:
  push:
    branches:
      - release
    paths:
      - .github/workflows/app-hal9*
      - apps/hal9/**

Thanks!
