chore: open an issue if publishing bb fails (#8223)

This PR adds a `build-check` step to the release workflow. This step
just checks whether any of the previous steps have failed and if so,
raises an issue before failing itself, otherwise we continue on to
uploading the release artifacts.

I've added @ludamad and @PhilWindle as people who would be assigned to
the created issue. Feel free to adjust this to whoever would be most
appropriate.

+The most recent nightly release failed. This means that no `bb` artifacts were published (which are required by Noir).

+Check the [{{env.WORKFLOW_NAME}}]({{env.WORKFLOW_URL}}) workflow for details.
