This PR clarifies the instructions in the “Printing those products” exercise in the Arrays lesson.

The existing Step 3 asks learners to start a for...of() loop, but does not clearly explain that the loop should wrap Parts 3–6 of the exercise. This can be confusing for beginners, as the placement of the opening and closing braces is not explicit.

The updated wording makes it clear where the loop should begin and which parts it should encompass, without changing any code logic or solutions.

Changes made

Updated Step 3 instructions to explicitly state that the for...of() loop wraps Parts 3–6.

No code changes; documentation-only clarification.
