Add support for <details> tag

It would be nice to have such an opportunity.

IE and Edge don't support this tag: https://caniuse.com/#feat=details
More infos about this new HTML element: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/details

So what you like to see in the editor is a block to toggle content?

[mukhammad-akilov]

IE is already dead.
Edge is moving to Chromium
It looks good even if the browser does not support the tag
I think The block must include two elements.

1. Title (only text)
2. Content (must be flexible for nested block elements)

We still support IE 11, see in the handbook, so we can't use the native <details> HTML tag at the moment.

I think it's a good idea for the future, but since it's not supported by all the browsers we support at the moment, I'm going to close for now. We should definitely revisit this later.
