Trigger DCA deployment when schematic releases or when `develop` branch gets updated

[linglp]

Is your feature request related to a problem? Please describe. Currently, we have to manually update DCA testing instance when the develop branch in schematic gets updated. We could modify our current github workflow so that it could send a post request to DCA's repo and redeploy DCA.

Changes that would need to happen:

On DCA github workflow:

• Find the workflow that controls deployment of the testing instance
• make sure that part of the workflow runs on repository_dispatch. See an example below:

  
  on:
  repository_dispatch:
  types: trigger-frontend
  jobs:
  build:
  name: Run stuff
  runs-on: ubuntu-latest
  steps:
    - name: deployment
      run: 'echo "Triggered event text: ${{ github.event.client_payload.text }}"'

On schematic github workflow: 
- triggers a post request like this: 

  - name: Test front-end deployment
    run: |
      curl -X POST \
      -H "Authorization: token ${{ secrets.ACCESS_TOKEN }}" \
      -H "Accept: application/vnd.github+json" \
      https://api.github.com/repos/Sage-Bionetworks/data_curator/dispatches \
      -d '{"event_type": "trigger-frontend", "client_payload": { "text": "develop branch has been updated"}}'

- the access_token here has to have scope `repo`
