Highlighted where `composer update` should be performed

Been a lot of activity in the chat lately due to people missing where `composer update` should be performed to link sprinkle sources. By bolding where this should be performed, it will (hopefully) stand out more and allow people to move onto bigger and better things more quickly. Should increase user retention too (first error is always a kill joy).
