Generate `script/storybook` (#3652)

[[PR Description]]

This PR adds the ability to run stories with `script/storybook`.

Running it directly will give you a selector like this:

```zsh
➜  zed git:(add-storybook-script) script/storybook
1) auto_height_editor	 9) icon		17) scroll
2) avatar		10) icon_button		18) tab
3) button		11) keybinding		19) tab_bar
4) checkbox		12) label		20) text
5) context_menu		13) list		21) viewport_units
6) cursor		14) list_header		22) z_index
7) disclosure		15) list_item		23) picker
8) focus		16) overflow_scroll
```

You can also provide a value like:

`script/storybook {STORY_NAME}` - Example: `script/storybook text`

OR 

`script/storybook components/{STORY_NAME}` - Example: `script/storybook
components/text`

I just wanted an easier way to interface with stories quickly to make
using them a bit easier, and enable discovery of what exists easier with
the selector.

This was a really quick hack, in the future we can extend this to a
proper CLI.
