Docs: Created ArgTypes component and stories

[tmeasday]

Issue: N/A

What I did

Created an ArgTypes block and stories to test it.

Questions:

• Does this block need to support the components prop?
• Does this block need to support the showComponent prop? If so, should it be a parameter (docs.argTypes.showComponent?)
• Does this block need to show the component / subcomponents in a separate tab?
• Does what this block does when you do of={meta} make sense?

How to test

See stories in chromatic / UI SB.

Does this block need to support the components prop?
Does this block need to support the showComponent prop? If so, should it be a parameter (docs.argTypes.showComponent?)

No, those are both undocumented features and we have discussed internally that we should just remove them entirely.

Does this block need to show the component / subcomponents in a separate tab?

Yes I would think so, we think people use that and we don't have an argument for removing it.

Does what this block does when you do of={meta} make sense?

It behaves as I would expect!

Ok, as discussed offline:

Does this block need to show the component / subcomponents in a separate tab?
Yes I would think so, we think people use that and we don't have an argument for removing it.

We are going to drop this concept for now (subcomponents). We are not going to show component props in the ArgTypes either (if passing of={story}).

Both will be supported until 8.0 in the legacy ArgsTable block. We will consider user feedback on whether we want to support them going forward in between now and then.
