feat(ui): group overloaded functions into tabs

[moshams272]

Description

This PR introduces a new tabbed UI for overloaded functions. This implementation is a direct result of the discussions in #1038. It updates the MDX AST to group overloads into OverloadTabs component(using tabs & react-tabs), utilizing CSS Grid stacking to prevent layout shifts; as it takes fixed height from the longest one.

Note: Using AI to write JSDocs & traverse some errors ;)

It's an interesting idea, but I think it makes searching harder, e.g. if I want to search for Buffer.from(buffer): Buffer, I need to make sure I'm on the right tab

Oddly enough, I'm fine with the showing of multiple overloads in our current state, and consumers can reformat their docs how they like.

Thanks for this demo, however :-)!

Hmm, fair enough! Thanks for your time 🤍
