Costum Classes in Sidebar component internal div

[DavideCamp]

Detailed description

Describe in detail the issue you're having.
I want to add classes on the internal div that show sidebar items (sidebar-item-content) for customization like width or border

    <div className={classes} {...other}>
       <div className={`${prefix}--sidebar-item-content`}>{sidebar}</div>
       <div className={`${prefix}--content-section`}>{children}</div>
    </div>

Is this a feature request (new component, new icon), a bug, or a general issue? Is a feature request

Is this issue related to a specific component? Sidebar component

What did you expect to happen? I expect to pass classes as Props for the internal div
What would you like to see changed? I would like to see the ... other props also be passed to the sidebar internal div (sidebar-item-content)

What version of the WFP UI (Carbon Design System) are you using? I'm using the new design system, the last version ( July 2024)

If you want i can create a PR with this new feature, Thanks
