Update the name of the workflow in the workflow_run trigger as
it was changed when adding cypress tests.
This will upload the preview build after running the cypress tests:
unsure if this is what we want or not. The preview build will be
slower to appear, but it does sort of make sense to only get a
preview buuild if the tests pass. If not, we might be able to do
this by doing a repository dispatch after the preview build.
* Use PR number directly in netlify github action
Looks like we can get the PR number for the workflow run that triggered
the workflow_run event, so there's no need for the massive faff we were
doing here.
* No need to create pr.json anymore
Switch to upstream and use a more recent version.
Fixes failure to edit on empty descriptions.
