• deps: update @​testing-library/dom to 6.0.0 (#​430) (1dd6544)

BREAKING CHANGES

• deps: If you were using debugDOM before, use prettyDOM instead. Note that debugDOM is different from debug which you get back from render. That is unchanged.
• cleanup: If your tests were not isolated before (and you referenced the same component between tests) then this change will break your tests. You should keep your tests isolated, but if you're unable/unwilling to do that right away, then you can either run your tests with the environment variable RTL_SKIP_AUTO_CLEANUP set to true or import @testing-library/react/pure instead of @testing-library/react.
• cleanup-after-each: If any of your code has import '@​testing-library/react/cleanup-after-each' then you need to remove that. It's happening automatically now.
