The #11921 update broke uploading coverage of the `main` branch (or
any in-repo pushes for that matter) to Codecov 4 months ago.
Version 4 requires an upload token to be provided and since there was
no configuration for it, the upload was failing. But the step itself
was showing up as successful due to `fail_ci_if_error: true` being
set. The error is visible in the console output, though.
This patch flips the setting to `fail_ci_if_error: false` and sets the
Codecov upload token in the config in clear text. The non-secret part
allows the PRs uploads to be more stable.
