Correct 4 patterns on documentation site to align with Link Guidance

[pikemurdy]

Multiple patterns are still built to display with three fancy links and/or stacked text links. They need to be corrected according to our guidance using a link group or maybe single text links?

Patterns IDed so far include:

1. Contact Card Banner aka Text & contact Smokey

• Adjust to one CTA link

2. Horizontal card

• Adjust to single link

3. Stacked card

• Adjust from text link list to single link
• Change default paragraph text to, "Stack Cards can be used to set important information apart from the rest of the page and collect links related to a single subject."

4. Text & Media + background banners

• Adjust from CTA links to to single link
• Change default paragraph text to “This pattern can be used to set important information apart from the rest of the page and collect links related to a single subject. Works well positioned above a footer.”

5. Media & Text with CTA and Text & Media with CTA

• Delete last 2 CTA Links from pattern (so only one is there by default).
• Change default paragraph text to “The Media & Text with CTA pattern is designed to fill the hero area of a high-level landing page, to orient users to what your page is about.”

6. Media & text banner

• Adjust from CTA link to single link
• Change default paragraph text to “This pattern can be used to set important information apart from the rest of the page and/or collect links related to a single subject.”

ETA: We have this guidance from Rachel that I don't think was ever signed off on.
