Closes #9202

Using the new GitHub Action for CodeCov to upload the code coverage report instead of the bash uploader.

The upload script also transforms the binary coverage data to a coverage xml report

That command would have to be executed

Is this coverage xml report also uploaded to CodeCov?

Thanks for working on this @mPandaRed. There's still some work needed; when it works, you should see the coverage reported for the PR.

I think only the XML is relevant here, so you should remove the first one.

Also, you need to generate coverage.xml, it is not generated automatically. See here.

Finally, if you decide to no longer use the scripts/upload-coverage.sh script, you should remove it from git.

The fix has been merged in #9252. Thanks anyway!
