fix: expand boolean attribute support (#15095)

* Adding test for expected boolean attribute support

* Improving support for more boolean attributes:

Added:
 - `defer`
 - `disablepictureinpicture`
 - `disableremoteplayback`

Improved:
 - `allowfullscreen`
 - `novalidate`

* Skipping JSDOM version of boolean attribute test

JSDOM lacks support for some attributes, so we'll skip it for now.

See:
 - `async`: https://github.com/jsdom/jsdom/issues/1564
 - `nomodule`: https://github.com/jsdom/jsdom/issues/2475
 - `autofocus`: https://github.com/jsdom/jsdom/issues/3041
 - `inert`: https://github.com/jsdom/jsdom/issues/3605
 - etc...: https://github.com/jestjs/jest/issues/139#issuecomment-592673550

* Adding changeset
