Fix template path - should be workflows/workflows/triage/

The checkout action with 'path: workflows' creates this structure:
- workflows/ (root of checked out repo)
- workflows/workflows/ (the workflows/ dir inside the repo)
- workflows/workflows/triage/ (the triage workflow)

So the template is at workflows/workflows/triage/templates/report.html,
not workflows/triage/templates/report.html.
