Token ignored on forked repo leading to failed coverage upload

Hi experts,

We are running into coverage upload failures, seemingly for a very similar reason to the issue https://github.com/codecov/feedback/issues/358#issuecomment-2151955137, which was fixed at the time by https://github.com/codecov/codecov-action/pull/1471.

Since today (could be related to release 4.6.0) we are running into a similar issue, where the token is ignored for forked repos and the upload fails because the token is required for protected branches, see https://github.com/facebook/Ax/actions/runs/11151452009/job/30994900275?pr=2813.

I'd appreciate your help with this.
