fix(review): de-stack blockquotes + drop vague timing in Task 7 callout

Convert the pre-existing 'These task numbers match...' blockquote into
regular prose so the new 'Task 7 credentials' 💡 callout no longer
stacks against another quote block. Drop the 'before the assignment is
due' clause: the next sentence already establishes the right trigger
('if you have not received it by the time you reach Task 7').
