[M-Adoo]

A pr from fork repository branch always failed:

Please provide the repository token to upload reports via `-t :repository-token`

workflow like this

pr from same repository branch is ok.

It is a known GitHub Actions issue: secrets are not shared for the forks, therefore ${{ secrets.CODECOV_TOKEN }} is not available for this build; here is a one of discussions about this thing: https://github.community/t5/GitHub-Actions/Make-secrets-available-to-builds-of-forks/m-p/30685

As it is unrelated to actions-rs, I'm going to close this issue.
