Disable validate_maintainers.

The validate_maintainers check has started to fail with the error:

```
HTTPError: HTTP Error 403: Forbidden
b'{"message":"Must have admin access to view repository collaborators.","documentation_url":"https://docs.github.com/rest/reference/repos#list-repository-collaborators"}'
```

Apparently GitHub has restricted the collaborators API to admins.  For now, this just disables the check to get CI working again.  Eventually, I think we'll just need to remove the check since we will unlikely use an admin token, and I don't see a workaround.  The `MAINTAINERS` list doesn't change often, so we may just need to put a sternly worded comment near the list.
