feat: add in github action to upload code coverage results

[wmundev]

For this github action to work, a repository secret must be added to this repo CODECOV_TOKEN

See https://docs.codecov.com/docs/quick-start#step-2-get-the-repository-upload-token

I added the token. I believe you have access to GitHub secrets however don’t have access to Codecov; I did not see a way to add you to Codecov.

thanks @twcclegg ! i think i only have access to create secrets through the gh rest api not through the web interface - https://docs.github.com/en/actions/security-guides/using-secrets-in-github-actions?tool=webui#creating-secrets-for-a-repository

all good though, i can figure out how to use the rest api next time
