Integrate SDDS base theme link component with XB

It would be good to do a side-by-side comparison with Storybook to see if it matches:

https://uikit.civictheme.io/

And ideally record the testing of all the props so we can see where the issues are to determine if the issues are on our end or on the XB end.

Here's a video of me messing around with it. It looks pretty good. I think there's an XB glitch where the starting props won't always display right. For example it starts with the disabled state prop being ticked. This one is actually false in the yml, so it's showing wrong, but then if you mess around with other props it actually selects it as true and the link goes grey. I think something similar could be happening for the button component.

I do wonder if that defaulting stuff may be related to other default/examples issues we are seeing. Let's not report this until the other XB bug is fixed though as maybe fixing that will fix this. Let's not close this issue (or we can open a separate one in our queue) so we don't lose this as an example of the bug.

I created this:

📌 Update SDDS components in base and subtheme so default and examples are the same Active

Add icons to the list to make a enum/select list.
