Add revealjs slides to Connect Cloud manual test fixtures

Follow-up to #14041. Adds a minimal revealjs presentation fixture
and includes it as Test 3 in the manual testing protocol, covering
reveal.js asset bundling verification.

Confirmed working: `quarto publish posit-connect-cloud` successfully
publishes revealjs slides with all assets intact.
