Your First 2D game: Creating the Enemy - randomize mod suggestion?

**Your Godot version:**
4.2.2

**Issue description:**

Currently, the tutorial shares this snippet:
```
func _ready():
var mob_types = $AnimatedSprite2D.sprite_frames.get_animation_names()
$AnimatedSprite2D.play(mob_types[randi() % mob_types.size()])

```

Thoughts on this?

```
func _ready():
var mob_types = $AnimatedSprite2D.sprite_frames.get_animation_names()
$AnimatedSprite2D.play(Array(mob_types).pick_random())
```

The `pick_random()` method is relatively straightforward to understand, and discussing the [Array](https://docs.godotengine.org/en/stable/classes/class_array.html) data type and its methods can be quite valuable for learning purposes.
