Periodic check on that the production dashboard is accessible

[L. Fernando De Pombo]

We use to have the job below that when deploying to staging would run the entire test suite, but it was quite flaky. We could write a smaller integration test that runs periodically in CI and probes the production dashboard

name: Deploy UI to staging

on:
  push:
    branches: [main]
  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
