Gino Valente bb968f41bc bevy_scene: Serialize entities to map (#6416) 
# Objective

Entities are unique, however, this is not reflected in the scene format. Currently, entities are stored in a list where a user could inadvertently create a duplicate of the same entity. 

## Solution

Switch from the list representation to a map representation for entities.

---

## Changelog

* The `entities` field in the scene format is now a map of entity ID to entity data

## Migration Guide

The scene format now stores its collection of entities in a map rather than a list:

```rust
// OLD
(
  entities: [
    (
      entity: 12,
      components: {
        "bevy_transform::components::transform::Transform": (
          translation: (
            x: 0.0,
            y: 0.0,
            z: 0.0
          ),
          rotation: (0.0, 0.0, 0.0, 1.0),
          scale: (
            x: 1.0,
            y: 1.0,
            z: 1.0
          ),
        ),
      },
    ),
  ],
)

// NEW
(
  entities: {
    12: (
      components: {
        "bevy_transform::components::transform::Transform": (
          translation: (
            x: 0.0,
            y: 0.0,
            z: 0.0
          ),
          rotation: (0.0, 0.0, 0.0, 1.0),
          scale: (
            x: 1.0,
            y: 1.0,
            z: 1.0
          ),
        ),
      },
    ),
  },
)
