Also don't use 'using namespace chrono' in snippets, but spell the types (nanoseconds, steady_clock) out in full. That doesn't break line-length limitations and makes it clearer (for the reader, and eventually, qdoc (when QTBUG-138535 lands) where each identifier comes from. Also remove the using namespace std::chrono_literals from the code snippets. They are repetitive and the linked cppreference.com gives all the available options how to import them, not just the one chosen here. Amends 12eacc3bab00f23d187a295b35e4a0d283ba85f4.
