Describe the bug
Our coverage uploads to codecov.io are throttled.

To Reproduce
https://github.com/google/syzkaller/actions/runs/9016979839/job/24774648282?pr=4790

Expected behavior
100% of the codecov.io uploads are successfull.

Additional context
Codecov.io is pushing customers to use tokenized uploads.
We don't use github secrets storage and I like it because there is no information to protect.
