[CI] Add manual trigger for updating Github pages to sycl-docs.yml (#20038)
I made PR #20026 yesterday to fix a bug in the benchmarking CI
dashboard, but looks like my changes were not deployed onto Github
pages.
This PR:
- Adds benchmarking dashboard to the list of paths in workflow triggers
- Adds a manual trigger to sycl-docs.yml, allowing people to manually
trigger a github pages update if necessary in the future
