trace2: increment event format version
In 64bc752 (trace2: add trace2_child_ready() to report on background children, 2021-09-20), we added a new "child_ready" event. In Documentation/technical/api-trace2.txt, we promise that adding a new event type will result in incrementing the trace2 event format version number, but this was not done. Correct this in code & docs. Signed-off-by: Josh Steadmon <steadmon@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
