docs(ace): correct comment — captureFrameNo is publicVariable'd

Drop the incorrect rationale about captureFrameNo being server-only;
clients receive it via publicVariable. The reason for the server-side
delayed send is simpler: getPosASL needs ~1s on the server to reflect
the settled position after ace_explosives_place fires.
