Attempted to make the nav bar closer in style to the old beta site / current main site. Adjusted the font weights, the size and position of the search bar, and the nav bar on the right. Also made the <li> tags for the curriculum and forum buttons clickable and change styles when hovered over, just like on the main freecodecamp.org site.

Partially solves https://github.com/freeCodeCamp/freeCodeCamp/issues/17266
