Ethan Palm 6c53a28e3a Document className and Tailwind arbitrary value support (#7301)
* Document className and Tailwind arbitrary value support

All built-in components now accept a className prop (mint#10540), and
dynamic Tailwind utilities work in className on MDX components
(mint#6737). Two pages stated the opposite.

- Correct the claims that Tailwind arbitrary values are unsupported in
  customize/custom-scripts and guides/custom-layouts
- Add className and arbitrary value guidance to the Tailwind section of
  custom-scripts, including the runtime-class limitation and the Tab
  content-panel caveat
- Add a Style components section to the components overview
- Add className property rows to every component reference page that
  supports it, and note the three components that do not
- Document inline Markdown support in component title props
- Correct the callouts page, which said typed callouts accept only
  children
- Replace inline style resizing with Tailwind classes in image embeds
- Add a help center article for Tailwind classes not applying in the
  editor's live preview, and note the limitation in custom-layouts
- Point skill.md at className before custom.css
- Accept className, keyframes, and unstyled in the Vale vocabulary

Resolves DOC-316, DOC-317
