ux: icon for landing page

[lidel]

Cosmetic, but we may want to use different icon for "Home page":

I clicked it many times as i expected something to dowload before I realized it is the default state for landing page.

@achingbrain maybe we could use "home" from https://github.com/ipfs-shipyard/ipfs-css?tab=readme-ov-file#icons?
