[ShapeUp] Redesign Landing Page

[andre-code]

Pitch on Notion

🤔 Problem

• The landing page does not well explain what Renku is, and why a user should get excited.
• Renku landing page should be more engaging → CTA
• It is not state-of-the-art
• I can not go back to the landing page when I am logged in (maybe solved in this build)

🚞 User stories / journeys

• As a RenkuLab user, I want a clear and compelling CTA on the landing page for confidently taking the next steps.
• As a RenkuLab user, I seek engaging content and visuals on the landing page that explain what Renku is, how it works, who is behind the platform, and why I should use it.
• As a RenkuLab user, I desire an enticing CTA that prompts action, whether it's trying Renku, signing up, or contacting them via email.
