fix(toc): remove horizontal overflow due Table of Contents (#23052) (#23068)

<!--Delete sections as needed -->

## Description

<!-- Tell us what you did and why -->
This PR fixes the horizontal overflow issue in the Docker Docs Website
due to overflow Table of Contents section, as described in
[#23052](#23052).

### Changes made:
Updated layout structure and/or styles in:
- layouts/partials/aside.html
- layouts/partials/content-default.html

The fix prevents excessive width in the ToC container, which was
previously causing the entire page to become horizontally scrollable on
certain pages.
