The words "image" and "texture" are used interchangeably in some doc comments

## How can Bevy's documentation be improved?

The words "image" and "texture" are used interchangeably in some of the doc comments, example from `ImageScaleMode`:

```
/// Controls how the image is altered when scaled.
#[derive(Component, Debug, Clone, Reflect)]
#[reflect(Component, Debug)]
pub enum ImageScaleMode {
/// The texture will be cut in 9 slices, keeping the texture in proportions on resize
Sliced(TextureSlicer),
/// The texture will be repeated if stretched beyond `stretched_value`
Tiled {
/// Should the image repeat horizontally
tile_x: bool,
/// Should the image repeat vertically
tile_y: bool,
/// The texture will repeat when the ratio between the *drawing dimensions* of texture and the
/// *original texture size* are above this value.
stretch_value: f32,
},
}
```

It's not that anything is incorrect, but the `Image` and `Texture` types serve very different purposes in Bevy so there's potential for confusion and it feels a bit loose and inconsistant to me.
