Ability to turn off Tailwind section

### Clear and concise description of the problem

Couldn't find a way to turn off the `Design System/Tailwind` section inside Histoire.

### Suggested solution

A config option where you can specify if you want or not Tailwind to be included as a section.

### Alternative

_No response_

### Additional context

I'm trying to have a minimal UI library page which showcases only components, and I'd like to hide the low level design system tokens section that get included automatically.

Review Histoire's configuration and the `Design System/Tailwind` section entry point to determine how sections are registered and controlled. Add a configuration option that hides this section, then verify that a minimal UI library can display its components without the design system tokens section.
