colorSpace

### What information was incorrect, unhelpful, or incomplete?

In [this PR](https://github.com/whatwg/html/pull/11529) that is landing presently, we are adding two more entries to the `PredefinedColorSpace` enum.

MDN doesn't currently have a page for `PredefinedColorSpace`. Rather, each instance where it is used lists all possible enum values.

I believe that the exhaustive list is:
* [HTMLCanvasElement getContext](https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/getContext#colorspace)
* [2D canvas getContextAttributes](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/getContextAttributes#colorspace)
* [WebGL unpackColorSpace](https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/unpackColorSpace)
* [WebGL drawingBufferColorSpace](https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/drawingBufferColorSpace)
* [ImageData attribute](https://developer.mozilla.org/en-US/docs/Web/API/ImageData/colorSpace)
* [ImageData constructor](https://developer.mozilla.org/en-US/docs/Web/API/ImageData/ImageData#colorspace)
* [WebGPU importExternalTexture](https://developer.mozilla.org/en-US/docs/Web/API/GPUDevice/importExternalTexture#colorspace)
* [WebGPU copyExternalImageToTexture](https://developer.mozilla.org/en-US/docs/Web/API/GPUQueue/copyExternalImageToTexture#colorspace)
* [WebGPU canvas configuration](https://developer.mozilla.org/en-US/docs/Web/API/GPUCanvasContext/configure#colorspace)

### What did you expect to see?

Each instance just includes `srgb` and `display-p3`. The spaces `srgb-linear` and `display-p3-linear` need to be added.
