Create a detektor validator for our styleguide rule for with blocks:

// Good
with(brandOrder.incomingPayment) {
  assertThat(state).isEqualTo(State.COMPLETE)
  assertThat(amountCents).isEqualTo(4_42L)
}

// Bad (only 1 action on the receiver)
with(brandOrder.incomingPayment) {
  assertThat(state).isEqualTo(State.COMPLETE)
}
