chore: use codecov token instead of OIDC

[iliapolo]

For PR from forks, OIDC doesn't currently work with the latest version of the GitHub Action.

Example failure:

Run codecov/codecov-action@v4
Error: Codecov: Failed to get OIDC token with url: https://codecov.io/. Error message: Unable to get ACTIONS_ID_TOKEN_REQUEST_URL env variable

See https://github.com/codecov/codecov-action/issues/1594

Revert back to token until we validate a fix.
