feat(homepage): add floating variant

[seaerchin]

Problem

We have a floating variant of the homepage with extra padding on side. This PR adds that in; this PR also fixes a erroneously placed button, where it should be placed outside of the div to maintain same structure

Solution

1. use same components for floating homepage but add a div wrapper
2. shift HeroButton out
3. shift conditional to not be included in div with className=mb8

Tests

• select floating variant
• preview should update
• select dropdown for hero interaction
• update options/title
• change order
• preview should update
• do the same for highlight
• chnage order
• preview should update
• repeat on diff screen sizes
• preview also shud update
