* Update Jest to more recent release
I want to use things like `jest.advanceTimersByTimeAsync`
* more jest updates
* add dep on types/prettier
* fix LegacyRoomHeader-test
* fix MatrixChat-test
* fix RoomView-test
* fix PollHistory-test
* update SidebarUserSettingsTab-test
* fix PipContainer-test
* fix UserOnboardingPage-test
* fix WidgetContextMenu-test.tsx
* Avoid `mockImplementation` for mock `matchMedia` impl
`mockImplementation` is (now) reset by `jest.resetAllMocks` and
`jest.restoreAllMocks`, which we don't really want here.
Fixes `theme-test`
* Move `mediaDevices` mock out of `setupManualMocks`
This doesn't work well in test suites with multiple tests, because the
`mockReturnValue` is reset for subsequent tests.
In any case, having it mocked out automagically is *magical*. Let's make it
opt-in.
* fix FormattingButtons-test.tsx

* clarify ts-ignore
