fix: display prop TypeScript issue (#636)

Potential typing BREAKING CHANGE: fix the `display` prop type. 
It shouldn't be a breaking change, but if you were patching the package this might break your CI so we're releasing it as a breaking change just to be on the safe side :) 
To verify it, just update to this version and re-run the typecheck script of your app: if it works, you're good to go 👍
