Looks good! Can we please get a changeset with details on the change, what to expect, what to do to migrate, etc.?

We could change all the foreground prop names to text in core/lib/makeswift/components/site-theme/components/button.ts to avoid needing to declare a new --button-primary-text css variable here. We're already building the css variables from the Makeswift control values via themeToCssVars(), so I would prefer to see that functionality not overridden if we can avoid the extra complexity of doing so.
