[BEEEP] [PM-10132] Upgrade storybook to v8 (#10288)

Upgrade storybook to version v8 which is a major upgrade. Storybook provides an
upgrade wizard which did most of the work.

- Ran npx storybook upgrade.
- Manually updated `remark-gfm` since the newer mdx requires v 4.
- Migrated all old stories still using `Story` to `StoryObj`.
