packages/react/src/Select/Select.tsx:40

• The contrast prop is still declared in the SelectProps interface (elsewhere) but has been removed from use—ensure it's also removed from the type definition and any public API docs to avoid exposing an unused prop.

packages/react/src/Select/Select.tsx:54

• Since contrast is no longer forwarded to TextInputWrapper, remove its mention from component documentation, PropTables (e.g., Storybook), and any related tests to keep docs in sync with the API.

Just left a comment around how to sequence breaking changes, let me know what you think!

With this change, would we also want to Omit contrast from the StyledWrapperProps, as well, so it doesn't show up in the type info? (I think that's where it comes from but don't quote me on that lol)
