Diff coverage

Checks that the added and modified lines are covered by unit tests

The line numbers are obtained by parsing the patch chunks of each file given by git diff

The coverage is obtained from an artifact previously uploaded. It must be an artifact named coverageArtifact containing the file coverage-final.json.

NOTE: Requires having used actions/checkout@v4 in a previous step.
