[bisq-network/bisq-website] Add search to menu bar (#411)

[m52go]

Hey thanks for the effort! 

Few notes:
- search results don't seem to open in a new tab
- styling
  - positioning: seems a little sloppy at the moment; too close to language selector and too far from dark mode toggle [0]
  - styling: seems to be taking on hover effects of other nav menu items (e.g., underlining)
  - dark mode: background color should probably be a bit darker, maybe #1a1a1a
