RectLight panic if Transform scale is 0

## Bevy version and features
version: 0.19.0
features: area_light_luts, debug

## What you did

I've been playing around with `RectLight` for a project of mine and found out that it generates a panic if any axis of its `Transform` scale is set to zero.

Here's the minimal required code to reproduce it:
```rust
use bevy::prelude::*;

fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Startup, setup_scene)
.run();
}

fn setup_scene(mut commands: Commands) {
commands.spawn((
Camera3d::default(),
Transform::from_translation(Vec3::new(0., 0., 10.)).looking_at(Vec3::ZERO, Vec3::Y),
));

commands.spawn((
RectLight::default(),
Transform::from_scale(Vec3::new(1., 0., 1.)),
));
}
```

## What went wrong

The code above generates a panic, with the following error:
```
thread 'Compute Task Pool (3)' (94093) panicked at /home/luca/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/bevy_math-0.19.0/src/direction.rs:66:9:
Error: The vector given to `Dir3::new_unchecked` is not normalized. The length is NaN.
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Encountered a panic in system `bevy_pbr::render::light::prepare_lights`!

```

## Additional information
I've already tried using `f32::MIN` instead of `0.` as the scale value, the issue remains the same.

Here is the backtrace for the error above:
```

```

Start with bevy_pbr::render::light::prepare_lights in bevy_pbr-0.19.0/src/render/light.rs, where the backtrace shows the panic, and trace its call to GlobalTransform::up in bevy_transform. Run the minimal RectLight example with a zero scale axis to reproduce it. Done means the example no longer panics for zero-scale RectLight transforms.
