fix(theming): update palette contrast types to current spec

Previous values used out-of-spec colors for contrast.
Low opacities values caused the design to not to meet AA standards
of minimum 4.5 contrast ratio for default text.

* Set hues with contrast type `light` to `strongLight`.
* Set contrast type for `green` `500` to `dark`.

Fixes #8992. Fixes #10164.
