chore: Minimize/remove front page banner

[darcywong00]

From Sept 2023 team planning meetings M4 review of websites

@mcdurdin suggested we minimize or remove the banner on the main page

For the goal of enabling users to quickly find the keyboard they're looking for.

[darcywong00]

Maybe a few possibilities (and open for A18 sprint design discussion)

• replace the banner with the keyboard search bar
• consolidate "Featured keyboads" with the footer

[darcywong00]

Maybe consolidating like this?
There would be more padding below the searchbar (unsure if we want to duplicate the search hints from https://keyman.com/keyboards/

[darcywong00]

need UX to revamp main page
maybe move the searchbar near the top of the gray portion

start typing, replace the language list with the search results. Scrollbar on the language list
