fix:[skip e2e] make more retries on codecov uploader (#33683)

fix #32235

inspired by
https://github.com/Kong/kubernetes-testing-framework/blob/main/.github/workflows/tests.yaml#L53-L69

### What is changing:
Introducing the
[wretry.action](https://github.com/Wandalen/wretry.action) to
automatically retry the
[codecov-action](https://github.com/codecov/codecov-action) in our CI/CD
pipeline. This change is intended to enhance the robustness of our
workflow by mitigating transient failures in the codecov-action.

### Follow-up changes needed:
This retry mechanism will be removed once the issue
[codecov/codecov-action#926](https://github.com/codecov/codecov-action/issues/926)
is resolved or if GitHub Actions provides a built-in retry feature for
actions.
