debugger error first_3d_game/09.adding_animations.rst

**Your Godot version:**
Godot Engine v4.3.stable.mono.official.77dcf97d8

**Issue description:**
At the final step of the [Your first 3D game](https://docs.godotengine.org/en/stable/getting_started/first_3d_game/index.html) guide, the finished game outputs a debug error:
```console
Warning: Integer division, decimal part will be discarded.
INTEGER_DIVISION
mob.gd:31
```

**As a result of** [this](https://docs.godotengine.org/en/stable/getting_started/first_3d_game/09.adding_animations.html#codecell4) **code:**
```gdscript
func initialize(start_position, player_position):
#...
$AnimationPlayer.speed_scale = random_speed / min_speed
```
**URL to the documentation page (if already existing):**
https://docs.godotengine.org/en/stable/getting_started/first_3d_game/09.adding_animations.html#codecell4

**Solution:**
In ``mob.gd``, replace:
```gdscript
# Minimum speed of the mob in meters per second.
@export var min_speed = 10
# Maximum speed of the mob in meters per second.
@export var max_speed = 18
```

With:
```gdscript
# Minimum speed of the mob in meters per second.
@export var min_speed = 10.0
# Maximum speed of the mob in meters per second.
@export var max_speed = 18.0
```

I've opened this as an issue because I don't know if this is the correct way of resolving this error
...or if it even needs fixing(?)

Looking forward to learn about this :) It's my first time using godot
