Ability to pass a ref through a search bar component

[eal172]

Could we add the option to pass a ref through the search bar component to the search bar input? This functions based on the input can be set up through ref and not class

Link component currently does this https://github.com/yext/js/blob/main/packages/sites-components/src/components/link/link.tsx#L23

Would also be helpful for other components like Facets
