Add test coverage report to build.

Need to think about this:

      - name: Add coverage to PR
        id: jacoco
        uses: madrapps/jacoco-report@v1.3
        with:
          paths: |
            ${{ github.workspace }}/itf-extension-maven/target/site/jacoco/jacoco.xml
          token: ${{ secrets.GITHUB_TOKEN }}
          debug-mode: true
