Add override to normalise paragraph spacing
Add override to normalise paragraph spacing

 - There's a clash between `content-block` styles from Static and the Govspeak
   component from the gem which alters the spacing between a heading and the
   next paragraph. This change makes sure that the spacing is correct when
   both `content-block` styles and Govspeak component are used together.
