[TRIVIAL] Retry codecov uploads

[Bronek]

High Level Overview of Change

As a workaround for spurious codecov upload errors, wrap codecov/codecov-action@v3 into a wandalen/[email protected] action

Context of Change

Spurious codecov upload errors are documented and expected in public repos which rely on PRs via forks, like we do. The underlying cause is API rate-limiting on GitHub due to the lack of access to CODECOV_TOKEN secret from the PR branches on forks. Although the suggested fix is to make the CODECOV_TOKEN effectively public, this comes with security implications which we yet need to consider. Retrying uploads is a decent workaround, which we can apply easily.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Refactor (non-breaking change that only restructures code)
• Performance (increase or change in throughput and/or latency)
• Tests (you added tests for code that already exists, or your new feature included in this PR)
• Documentation update
• Chore (no impact to binary, e.g. .gitignore, formatting, dropping support for older tooling)
• Release
