feat: upgrade jest to 30 (#3152)

- Upgrade Jest deps in `examples`
- Remove `ng-jest-resolver`
- Replace custom `jest-env-jsdom-abstract` with `@jest/environment-jsdom-abstract`

BREAKING CHANGE

- Jest 30 is required
- Minimum supported version for JSDOM is 26
- `ng-jest-resolver` is no longer needed for Jest 30 therefore it was removed
