Feature/landing page update

[codespool]

Redesign the landing page according to design: https://www.figma.com/design/iWhh82EIXNR9EVSkc9sHAG/Astar-Docs?node-id=340-21&t=6nixgtL6wnmJAuwj-0

• customise header and footer
• implement custom search (swizzle the native algolia docusearch component)
• implement tab and dropdown menus

After CSS inconsistencies in the prod build:

• upgrade and lock all dependencies
• remove sass plugin
• modify build command so minifier is not breaking css
• fix case-insensitive links
• image and styles cleanup
• additional css updates:
  • consistent background color
  • background image
  • borders and small tweaks
