refactor(how-it-works): slim repetitive 'no SDK' boilerplate

The 'no code changes / no SDK / no rewrite' line is already said
clearly in the Hero subhead and the WhyUs cards. Repeating it on
step 1 of HowItWorks adds nothing. Step 3's tail 'Nothing to
instrument. Nothing to maintain.' is two sentences saying the
same thing — both removed.
