Add job summary

[benkeil]

It would nice if the plugin could create a job summary. Like that it's easier to see what the job has done, without digging into the logs.

You can add your own by using the outputs provided by the action:

- name: Summary with release
  if: ${{ steps.release.outputs.new_release_published == 'true' }}
  run: |
    echo "# :white_check_mark: New release published" >> $GITHUB_STEP_SUMMARY
    echo "" >> $GITHUB_STEP_SUMMARY
    echo "Release bumped from v${{ steps.release.outputs.last_release_version }} to v${{ steps.release.outputs.new_release_version }}" >> $GITHUB_STEP_SUMMARY
    echo "" >> $GITHUB_STEP_SUMMARY
    echo "## CHANGELOG" >> $GITHUB_STEP_SUMMARY
    echo ""
    echo "${{ steps.release.outputs.new_release_notes }}" >>$GITHUB_STEP_SUMMARY
