[UwU] About page redesign (#711)

- Combines about page into a single MDX file per translation
- Adds a license component for sticker attribution

---

- **TODO:** code blocks in the license dialog aren't being processed by
`unified` / `remark-shiki-twoslash` correctly in the deployment build,
resulting in incorrect styling (the "shiki" classes/spans aren't being
added). This works perfectly fine in dev mode. I have no clue what's
going on.
