Overview

I think it would be useful to add a link to the summary report (if included), once the action terminates (both if it succeeded or if it failed).

Users might not know that a summary report is generated and might try to look for failures through the whole output, which can be quite verbose and harder to understand. I think a link to the summary report would simplify debugging operations.

Possible implementation

Add a step after run-lychee to the action.yml that logs the summary report:

- name: Log summary
   if: always() && inputs.JOBSUMMARY == true
   shell: bash
   env:
     SUMMARY_URL: '${{ github.server_url }}/${{ github.repository }}/actions/runs/${{ github.run_id }}#summary-${{job.check_run_id}}'
   run: echo "Summary report: ${{ env.SUMMARY_URL }}"

Happy to open a PR if this sounds like a good addition.
