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 :-)!

[moshams272]

Hmm, fair enough! Thanks for your time 🤍

I actually have a different opinion and was thinking of this differently. Instead of the simple 1, 2 on the Overload headers which makes distinction hard, I feel that it could look like Code Tabs; So it becomes pretty apparent that there are more versions of this method.

What it means is that the main method signature is always the same (the initial tiny snippet box under the header) and only the attributes and descriptions/etc are under "codetabs"

I still feel that this would be much simpler.

and consumers can reformat their docs how they like.

Well I do feel our web generator could have a default stance on overloads, as it is already an opinionated style.

That much I agree. I think that anchorinhg can be solved with the tab being switched to the right one based on the click... For pure command+f/ctrl+f searches, I'm unsure of either, we could either think a bit more about this or keep the current status quo.

My goal was to make overloads simpler to identify / consume less vertical space and be better organized.

I initially thought about using the signatures/parameters as the tab titles, but I hit two major edge cases:

• Extremely long parameters: If an overload has 4-5 parameters or long variable names, the tab title becomes massive and completely breaks the UI. (AugustinMauroy actually pointed out a similar issue).

• Identical signature, different types: If we only show the signature, the tabs will look identical!

That's why I retreated to indexes, and to make clear that tabs are for overloads, I've placed a header before the component itself (above indexes) contains "Overloads".

After Aviv's comment, I searched about it and found that the web standard solution is using
Accordion(details & summary tags) , It'll solve the search problem but it'll be vertical, not horizontal. we can put the signature also, but I imagined that design and I hate it, so I closed this PR ;)
