This is regarding theming updates that need to happen to nearly all auro components

Describe the solution you'd like

1. All tokens with the prefix --auro need to be renamed to --ds so they work with the new WCSS v5 update.
2. The WCSS package needs to be updated to ^5.0.0 and the import paths in the component *.scss files need to be updated as well

Describe alternatives you've considered

None

Additional context
