Add animations to logo and splash image

[alexieyizhe]

This is a super nice to have but the splash image on the main landing page would be super cool if it was animated

• have the stars popping up like people are rating them!
• use lottie?
• idk how to do animation lol

The + on the logo should fly in on animation - @angelinajin

so this is a thing that I now want to implement as well lol^^
