Update Contact Details pattern examples with link styling

[navkaur76]

Visual underline to indicate link styling is currently missing from the Contact Details stickersheet. The email address within the examples should be displayed with an underline.

Design effort:

• Figma stickersheet: update the default examples to display the example email address as a link. Note: not the list or list group examples.
• Pattern page: update examples and any relevant annotations

Dev effort:

• Storybook examples update (functional + visual change)
• Site pattern page update
