deps(ui): Upgrade jest, jest-junit

[scttcper]

Jest is working towards releasing v28 so this puts us on the latest version of 27

[JonasBa]

@scttcper we should run a quick benchmark of the test suites before merging this. The reason is that lots of people have been saying that there seems to have been slight regressions in v27 (jestjs/jest#7963). If those are sufficiently large for our project, we should maybe reconsider merging (altho looks like all of our tests pass, so maybe there's no impact)

[scttcper]

@JonasBa we're already on v27. Do the comments say it's the later versions or any version

@scttcper oh my bad. I looked at the @types/jest diff which was still on 26...
