Upgrade Testing Library DOM #524
Description
Upgrade Testing Library DOM to the latest major (https://github.com/testing-library/dom-testing-library/releases/tag/v8.0.0).
This will definitely be part of 5.0, but one related breaking change I'm considering is also moving @testing-libarary/dom to peerDependencies since once we drop the legacy ElementHandle implementation, we should no longer no need to bundle the UMD build with Playwright Testing Library.
