Remove deprecated properties from api-stories

[yannbf]

It's unclear whether to remove these deprecated properties from the api-stories module in Storybook 8:

storybook/code/lib/types/src/modules/api-stories.ts

Line 13 in bf63829

/** @deprecated */

@ndelangen @shilman please let us know whenever you can, and what should be done migration-wise 🙏

[shilman]

Yes please remove them. They are superceded by type: 'root' | 'group' | 'component' | 'docs' | 'story'

[yannbf]

@shilman can you explain what this code becomes?

useEffect(() => {
    if (api && props.isHighlighted && item.isComponent) { // <-- this becomes `item.type === 'component'` I assume
      api.emit(
        PRELOAD_ENTRIES,
        { ids: [item.isLeaf ? item.id : item.children[0]] }, // what about item.isLeaf? maybe a combination of checking parent and no children?
        { options: { target: item.refId } }
      );
    }
  }, [props.isHighlighted, item]);

[ndelangen]

isLeaf = 'docs' | 'story', I think.

Reminder to shelve this until the storyStoreV6 work is done.
