docs: M5d-2: after gate: ok, do not sum test results

Task 01 told Ornith to add up every `test result:` N passed. A greedy
sed kept the last digit (1512 became 1022) and it stopped with the
correct T1 and given test uncommitted. T50/T59: the last line of
make gate is the count; summing is not a stop.
