Add false to ResizableProps.enable

[inokawa]

Proposed solution

In current behavior, all resizers are disabled if we pass false to ResizableProps.enable.

re-resizable/src/index.tsx

Lines 888 to 890 in da458ab

	if (!enable) {
	return null;
	}

However current type definition does not accept false so I fixed the type.

Tradeoffs

N/A

Testing Done

Tested with passing false to actual Resizable component.
