Make this application work with repos in the nearform-actions organization

Now that we're moving repos to the nearform-actions org, we should make this work against that organization as well. We need to figure out what needs to be done for that to happen, and make changes accordingly.

To further clarify this, we want the app to be able to pick up failed pull request checks from nearform-actions organization and attach them to nearform technology hub board.

We discussed this with @simoneb and there are some limitations to be considered:

1. We can't install this app on nearform-actions organisation because we would have to make the app public.
2. We certainly don't want two instances of the same app running in a GCP.
3. Currently the app only knows how to get information about a pull request from the nearform organization, because that's where the app is installed. We need to query the pull request details to see if the author of the pull request was dependabot.

One idea that we had was to create a separate app installed in the nearform-actions that would listen for the pull_request and check_suite events and send those over to the app installed in a nearform organization and somehow do the processing in that app.

Also it's not very easy to get this app running locally which makes the testing bit difficult.
