Add props for Dialog to disable Escape to close and click overlay to close

[futantan]

When we need user to confirm from two dangerous options, he/she must select from these options, how about add two props:

• closeOnEsc default true
• closeOnOverlayClick default true

Just like https://chakra-ui.com/docs/components/modal/props

Willing to help if this proposal is approved

I can understand the motivation behind this, but this library is a port of headlessui and there are no plans to add more functionality beyond what exists in that library. Keeping up with upstream is a tough enough challenge by itself. Sorry!
