It’s jsx which is framework agnostic and used in several frameworks but most closely associated with react. It’s easy to convert to html but I guess the author is a react dev and also these icons use framer-motion which is a react animation library to animate the cursor hover. Looks like you can strip those out if you wanted to use these icons in html without animations.

As much as I love federated socials (or that they exist anyway), they’re almost never going to be the tool to grow your business.
