Implement a repository dispatch to run the tests automatically

[smcastro]

Implement a repository dispatch in xradio to send a signal when there is a merge to main. The signal will be received by benchviper to execute the workflow that runs the benchmark tests. A few steps are needed for this to work:

Pre-work
There is currently a secret configured in xradio called DISPATCH_TOKEN to work with testviper. That token should be renamed to include a namespace appropriated to that dispatch.

Work on this repo

• Enable a secret such as above in xradio and in benchviper.
• Update the workflow in https://github.com/casangi/toolviper/blob/main/.github/workflows/python-testing-integration-template.yml and include a dispatch sender similar to the one below, implemented for testviper in lines 140 ~ 192 and also replace the variables github.repository with xradio as for now we are only accepting dispatches from xradio.

  dispatch-integration-tests:
    runs-on: ubuntu-latest
    needs: test-all
    if: github.event_name == 'push' && github.ref == 'refs/heads/main'

• Create a receiver workflow in benchviper similar to this one https://github.com/casangi/testviper/blob/main/.github/workflows/dispatch-receiver.yml.

Open points

• There should be a way to notify xradio when benchmarking tests fail in benchviper.
• To start one can add a badge in https://github.com/casangi/xradio/blob/main/README.md pointing to the html pages published in this repository showing the test results.
