ci: Integrating CodeCov with NGO repo [develop-2.0.0] (#3474)

Recently CodeCov was improved to also work for GitHub.com repositories
so we can finally update the configuration to upload our results.
This PR should be merged after we will be done with ongoing release
process because it may require some corrections in the way how CodeCov
comments will work so I don't want to block any ongoing work

## Backport
This is ported to `develop` branch in
#3476.
Note that it will not affect `develop-2.0.0` branch since the
configuration is being taken from default branch (currently `develop`)
but when in the future we will switch the default branch then the
configuration will already be there
