[Legend] Enable overflow scrolling with pagination

[techniq]

While you can enable overflow scrolling using:

<Legend placement="top-left" classes={{ root: 'right-0 overflow-auto scrollbar-none' }} />

it would be nice if there was also arrows shown dynamically when overflow exists, and click on it steps left/right 1 page (similar to MUI's Scrollable Tabs and Skeleton's Multi-Column examples).
