Unmute ingest YAML tests (elastic#122319) (elastic#122457)

These tests were already fixed by elastic#116200. The failing builds that the
bot linked when it muted the test all didn't contain the fixing commit
of that PR -- so it was just unfortunate timing.

Closes elastic#116157
Closes elastic#116158
