Improve design tokens documentation #4435
Description
Follow-up to #4362
Improve the effectiveness of the all tokens page by finding a way to group tokens by concept (colors, spacers, breakpoints, etc.). This may involve breaking the current table into multiple tables, adding a type column and filter, or something else. May even mean creating a new page/section, rather than replacing our current table.
Research other design system approaches and consider user research to help understand how people currently use & want to use this page.
