Arrow keys no longer expand and collapse parent nodes as expected since storybook actions were removed from the next story

The component story also now takes up the full width of the container and does not properly display the custom story styles in https://github.com/carbon-design-system/carbon/blob/main/packages/react/src/components/TreeView/next/story.scss

CodeSandbox example

Steps to reproduce

try to expand and collapse a parent node with the arrow keys and check the console for errors
