Update color tokens for theming support

[jordanjones243]

General Support Request

In order to make Auro components themeable, we need to make sure there are no hard-coded and correct semanticly named tokens within the component. There also needs to be investigation around border rules which have a combination of size and color tokens, making them more complex, as well as background-color and color rules.

Possible Solution

Work with designers to figure out what tokens need updated values or renamed.

Additional context

This work stems from theming work happening to all Auro components:

• https://github.com/AlaskaAirlines/AuroDesignTokens/issues/147

Rules and tokens to be edited can be found in the comments.

Exit Criteria

All hardcoded values and tier 1 tokens (brand tokens), are removed and replaced by semanticly named tier 2 and 3 tokens

• Hardcoded
  • Accent icon transition: transition: all .3s cubic-bezier(.215, .61, .355, 1);

This ticket is not needed anymore, as the rule listed above is not a color token.
