codecov tries to fetch oidc token also on PR from fork

[shahar-h]

When running codecov action v4.4.0 with oidc enabled on PR from fork, it tries to fetch oidc token and fails:

Run codecov/codecov-action@6d798873df2b1b8e5846dba6fb86631229fbcb17
  with:
    fail_ci_if_error: true
    files: ./coverage.xml
    name: codecov-envoy-gateway
    verbose: true
    use_oidc: true
Error: Codecov: Failed to get OIDC token with url: https://codecov.io./ Error message: Unable to get ACTIONS_ID_TOKEN_REQUEST_URL env variable

According to #1404 I expect it to skip token fetching and use tokenless request.
My temporary workaround is to set use_oidc to true only on push event or on PR from the same repo:

use_oidc: ${{ github.event_name == 'push' || (github.event_name == 'pull_request' && github.event.pull_request.head.repo.full_name == github.repository) }}
