Request ttl output now that generation is fixed

Adds --output-formats ttl to the _test-examples recipe now that the
previous commit's fixes make it succeed cleanly, and updates the CI
comment that used to explain (and justify) skipping it -- also correcting
its now-stale claim that examples/output/ is git-ignored.
