Automatic deletion of "GHSA" repositories under GitHub organization

[sethmlarson]

After a GHSA ticket has been closed for some time (3 months?) the corresponding GHSA repository, if any, can be removed. This is because GitHub creates a new repository for every GHSA ticket and the number of repositories under the organization would grow without bound.

The name of these repositories matches cpython-ghsa-[a-z0-9]{4}-[a-z0-9]{4}-[a-z0-9]{4}.

We're delaying this as there is no API access to GHSA repositories, would require Playwright so probably not worth it as extra repos don't actually bother us?

@sethmlarson will open a GitHub feature request for this
