[ci]: continue-on-error for more gh auth status checks (#90890)
This seems to be failing for our deploy test workflow
([x-ref](https://github.com/vercel/next.js/actions/runs/22685809647/job/65778800145)).
Updating to `continue-on-error` similar to
https://github.com/vercel/next.js/pull/89098 because this check doesn't
seem reliable.
If it fixes, will just remove in both spots all together.
