Issue:
Upgrade test/demo projects to Jest 28
Probably boils down to our example projects (might be even just `demo-react-native-jest`)

Pull request description:
chore: upgrade internally to jest@28
## Description

**Maintenance PR.**
Upgrades all the sub-projects internally to Jest 28 (fixes #3396)

It has a couple of issues, though:

1. Error stack traces have changed slightly in Jest 28, so I had to update some expectations in the unit tests related to our error mangling utilities.
2. There's an issue with dropping redundant `@types/jest` devDependencies at the moment. Trying to solve it here: https://github.com/kulshekhar/ts-jest/pull/3513
3. There's a weird import glitch for `require("yargs/yargs").Parser` – created a bug report to Jest: https://github.com/facebook/jest/issues/12843

All the issues have been resolved via various workarounds, but this makes me wary about merging this PR soon. I'd wait for some official responses above.
