Problem with dark themes' `$ui-02` and '$ui-03` values are the same

Problem:

Dark theme’s $ui-02 and '$ui-03` are the same.

$ui-02

It appears $ui-02 has the same usage and values as $field-02 on all themes. Potentially we can drop $ui-02 if there’s never a use case for it.

$ui-03

$ui-03 are showing up in the following places:

• Accordion, divider lines
• Code snippet with numbers, divider line on the left between num and code
• Tabs, underline for unselected
• Progress indicator, progress bar
• Pagination, divider lines
• Overflow, rule
• Data table, header bar

I would be fine with calling this new token decorative-01 until we audit our token naming for v11.

Values per theme:

White	G10	G90	G100
G20 #e0e0e0	G20 #e0e0e0	G60 #6f6f6f	G70 #525252

Oh right sorry, reread above comments ^ we will need to create a new token to use instead of updating ui-03 token values. We don’t want to update values for ui-03 because then it will affect components negatively across the board that don’t have a light prop.
