docs: Work around unplugin bug

[dwgray]

Describe the PR

It looks like unplugin-vue-components has a bug where it doesn't correctly handle <script setup='ts'> in vitepress (possibly in SSR mode in general). I will continue to refine unplugin/unplugin-vue-components#801 and see if I can get an upstream fix, but this workaround gets us up and running again.

All the docs that were depending on unplugin-vue-component now use <script> rather than <script setup> sections. Since all we're doing in these files is importing data for the component reference, this still seems like a big win over not using unplugin-vue-component.

I also started getting a circular reference error when using the tooltip composable, so I converted to the component.

Small replication

Look at the breadcrumb or carousel documentation under app\docs after doing a pnpm build followed by pnpm preview
