Docs: Args table overflows on mobile and causes horizontal page scroll

Description

The Args/Props table inside the Storybook Docs view is not responsive on mobile screens.
Some table cells (e.g. union types, controls column, long generic types) force the table to exceed the viewport width.

Because the table is not wrapped in a scrollable container, the entire Docs page becomes horizontally scrollable, instead of just the table.
This breaks the mobile layout and results in a poor user experience.

Steps to reproduce

1. Open Storybook.
2. Switch to Docs tab of any component (e.g. AutoComplete → Docs).
3. Set the viewport to ~375px (iPhone size).
4. Scroll to the Args table.
5. Observe that:
   • The table content overflows to the right
   • The table itself does not scroll
   • The whole page scrolls horizontally instead

Image of Bug

Start by reproducing the issue in the Storybook Docs Args/Props table at a 375px viewport, using a component such as AutoComplete and checking long union or generic types. Locate the table rendering and its surrounding layout, then verify that only the table scrolls horizontally while the Docs page remains fixed to the viewport.
