Tianlan Zhou b1a634cade Fix alpha channel in RGB32F image texture format conversion (#6914)
# Objective

The following code:

```rs
use bevy::prelude::Image;
use image::{ DynamicImage, GenericImage, Rgba };

fn main() {
    let mut dynamic_image = DynamicImage::new_rgb32f(1, 1);
    dynamic_image.put_pixel(0, 0, Rgba([1, 1, 1, 1]));
    
    let image = Image::from_dynamic(dynamic_image, false); // Panic!
    println!("{image:?}");
}
```

Can cause an assertion failed:

```
thread 'main' panicked at 'assertion failed: `(left == right)`
  left: `16`,
 right: `14`: Pixel data, size and format have to match', .../bevy_render-0.9.1/src/texture/image.rs:209:9
stack backtrace:

             at .../bevy_render-0.9.1/src/texture/image_texture_conversion.rs:159
   7: bevy_test::main
             at ./src/main.rs:8
...
```

It seems to be cause by a copypasta in `crates/bevy_render/src/texture/image_texture_conversion.rs`. Let's fix it.

## Solution

```diff
  // DynamicImage::ImageRgb32F(image) => {
- let a = u16::max_value();
+ let a = 1f32;
```

This will fix the conversion.

## Changelog

- Fixed the alpha channel of the `image::DynamicImage::ImageRgb32F` to `bevy_render::texture::Image` conversion in `bevy_render::texture::Image::from_dynamic()`.
