This patch adjusts the background-color/border/outline of the three different context menu buttons across the HNT page: top sites, pocket stories and recent activity cards.
It addresses the different link states: :hover, :focus (inlcuding :focus-visible), and :active for this button. This patch also includes attribute values for dark mode.
