We also change the folder structure of the browser unit tests, because we've removed the in-package integration tests (see #12967)
ref #11084
This change also removes
environment: 'jsdom'
from the central config in favour of explicitly adding jsdom environment via the@vitest-environment
pragma to the specific test file that needs it. This should means that our tests are not polluted with jsdom globals, and that future writers have to explicitly opt-in to the behaviour.
