Changing milestone_sm_finish from ATS_PROBE1 to ATS_PROBE2 is a USDT interface change: existing bpftrace/perf scripts that assume only arg0 (sm_id) will now see an additional arg1 (HTTP status). The repo documentation example still treats milestone_sm_finish as having a single argument (doc/developer-guide/debugging/tracing.en.rst around the bpftrace example), so it should be updated to reflect the new signature and describe arg1.

| ATS_PROBE1(milestone_sm_finish, sm_id); |

The example demonstrates the use of sm_id. It doesn't need to use status_code, and the bpftrace code should keep working as is.
