bug: ts2asl playground doesn't properly infer type information on Choice states

[Olaf Conijn]

the following code retains type information (used in choice state to create Numeric comparison).
however on the playground the type information seems to get lost and it will default to String comparison

export const numericComparison = asl.deploy.asStateMachine(async () => {
  const condition = 42;
  const items = [2, 42, 3];
  const listWithRetunrned = items.map(item => {
    if (item === condition) {
      return { returned: item };
    }
  });
  const item = listWithRetunrned.filter(x => x.returned);
  return item;
});
