Prior to v1 we changed naming of variants on Button (and ToggleGroup) from filled, outline, ghost to primary, secondary, tertiary.

This was primarily due to wanting to give a semantic recommendation on what type of buttons could be used as primary, etc action.

Some observations since v1 release;

• Solutions where having a "filled" button as "primary" is not necessarily correct and/our using "outline" is also correct.
• Users have mapped variants to other variants (several occasions back to filled, outline, ghost)
• We actually use descriptive names for all other variants (avatar, badge, card, details) on components except; button/togglegroup.
• What should be primary, secondary or tertiary, should be up to consumers to decide.

Suggest changing the variant names on Button back to being descriptive variant names filled, outline, ghost.
