What's the background?

For Modal component, when use it like Modal.method(), close icon will not display, but in practical, people may need a close icon for this dialog, so I made closable option for it, and default value is false.

API Realization (Optional if not new feature)

As the background say, we can show close icon like below:

Modal.info({
    title: 'This is a notification message',
    content: 'Hello Confirm Modal',
    closable: true,
})
