chore: bump Jest, remove flaky inline snapshot (#150)

Bumping Jest to latest, removed inline snapshot as there's a pending bug with trailing whitespaces inside of it being removed by IDEs (solution is to make them regular snapshots, but in this case the test was just plain unnecessary)

### Test plan
