ds-color-ui-default-inverse and ds-color-ui-hover-inverse already exist in our design tokens

ds-color-ui-default-inverse and ds-color-ui-hover-inverse already exist in our design tokens @jordanjones243 I was referring to the "color palette" page on the doc site and it seems like it's not fully up to date with the "design tokens" page. If it already exists, no need to add it! I'll edit the issue.
