Codecov for the main branch is not up to date

[shizhMSFT]

Since the CODECOV_TOKEN is missing, the codecov percentage has not been updated after the commit 2b6f94f, although the codecov for PRs are working properly (this is because PRs to public repos does not require a token).

Error log from https://github.com/veraison/go-cose/actions/runs/10406856016/job/28820855042#step:5:31:

Error: Codecov token not found. Please provide Codecov token with -t flag.
Warning: Codecov: Failed to properly create commit: The process '/home/runner/work/_actions/codecov/codecov-action/v4/dist/codecov' failed with exit code 1

To fix it, admins of the go-cose repository are requested to set the CODECOV_TOKEN in the repository secret. Detailed workflow can be found in #200 (comment) and #200 (comment).
