Add Partnership Logos to Landing Page

[Blaec-CoCalc]

Is your feature request related to a problem? Please describe: It's challenging for users to immediately recognize our strategic partnerships upon visiting the CoCalc landing page, potentially missing out on understanding the credibility and collaborations CoCalc maintains.

Describe the solution you'd like: Add logos of our partners (NVIDIA, Google, Hyperstack) to a designated section on the landing page to highlight these partnerships. Note: (Maybe we can do this with Cambridge University Press?)

Additional context: Displaying these logos can enhance user trust and attract interest from visitors familiar with these prominent companies, thereby increasing engagement and perceived value of CoCalc. We could also link the logos to blog posts about the partnership announcements, which could help with SEO.
