bench: restore the upstream gc_bug_bridge_flavor_traceback_names wasm baseline

`bench: re-record five jit-stats baselines` wrote guard_failures=1838 against the
pre-rebase base. #1061 had moved the same counter to 2037, and the rebase kept
the branch side. Local wasm reads 2037, and main's ubuntu job passes this bench
against its committed 2037, so the branch value was the stale one.
