Minor Changes

• #4979 a0e9ebcef Thanks @davidkpiano! - State IDs are now strongly typed as keys of snapshot.getMeta() for state machine actor snapshots.

  const machine = setup({
    // ...
  }).createMachine({
    id: 'root',
    initial: 'parentState',
    states: {
      parentState: {
        meta: {},
        initial: 'childState',
        states: {
          childState: {
            meta: {}
          },
          stateWithId: {
            id: 'state with id',
            meta: {}
          }
        }
      }
    }
  });
  
  const actor = createActor(machine);
  
  const metaValues = actor.getSnapshot().getMeta();
  
  // Auto-completed keys:
  metaValues.root;
  metaValues['root.parentState'];
  metaValues['root.parentState.childState'];
  metaValues['state with id'];
  
  // @ts-expect-error
  metaValues['root.parentState.stateWithId'];
  
  // @ts-expect-error
  metaValues['unknown state'];
