fix: use correct WordPress Modal component props

Fix modal that was persisting by using correct @wordpress/components
Modal API:
- Use 'open' instead of 'isOpen' prop
- Use 'onRequestClose' instead of 'onClose'
- Add 'isDismissible' to allow closing with ESC/outside click
- Add 'focusOnMount' for accessibility
- Add deprecation warning props for TextControl (__next40pxDefaultSize,
  __nextHasNoMarginBottom)
