Update the Portal component to use the new react portal api (when overflowBoundaryElement is used for position)

[bolivierjr]

Fixing Portal component by switching from ReactDOM.unstable_renderSubtreeIntoContainer to React.createPortal, so that the context from PortalSettings, carries through when having multiple layers of overflowBoundaryElement.

This would also get you one step closer to using react 18 in the future, since the ReactDOM unstable_renderSubtreeIntoContainer method will be deprecated and will need to change to the react portals api.

Fixes #3028
