[Bug]: Codecov v3 upload failing

Describe the bug

Currently, codecov upload is failing for our repo and a few others: codecov/codecov-action#1359

It looks like might be a bandwidth issue. However, I don't beloeve we shouldn't be caught in this as we use a codecov upload token. A few things to debug:

• bump codecov from v3 to v4
• Regenerate token

Steps to reproduce the behaviour

The root problem with this bug was a typo in the secret. This cause the token to not be used by the uploaded, defaulting to non-token uploading. This has now fixed.
