EmptyQwenImageLayeredLatentImage: 11 locales still describe `layers` wrong

## Summary

`comfyui_embedded_docs/docs/EmptyQwenImageLayeredLatentImage/` has 12 locales. The English source has been corrected in https://github.com/Comfy-Org/embedded-docs/pull/113; the other 11 still carry a description of the `layers` widget that is actively misleading, and none of them state what the extra slot in the output shape is.

## What is wrong

Every locale describes `layers` as some variant of "the number of additional layers to add to the latent structure, defining the depth of the latent representation", and every locale prints the output shape `[batch_size, 16, layers + 1, height // 8, width // 8]` without explaining the `+ 1`.

The `+ 1` is not padding or depth. Qwen-Image-Layered regenerates the full image in addition to the layers, so slot 0 is the full image, it is not one of the layers, and it should be discarded when only the layers are wanted. comfyanonymous, verbatim:

> it's a model specific thing, it's because this model is an image generation model that regenerates the full image and the layers
>
> so if you set layers to zero you get only the original image
>
> but if you set layers to 2 you get the original image + 2 layers
>
> the first image is exactly the same as the original and should be discarded
>
> and all the layers when composited together should recreate the original image

Verified against source: `comfy_extras/nodes_qwen.py:109-130` allocates `torch.zeros([batch_size, 16, layers + 1, height // 8, width // 8])`, and `layers` has `min=0`.

## Why this was not done in the same PR

`.cursorrules` in this repo is explicit:

> Do not automatically start translation work for other language files unless actively requested by the user

Machine-translating 11 locales without a reviewer who reads them would be worse than leaving them stale and tracked. Hence this issue.

## Note for whoever picks this up

`ja.md`, `ko.md` and `zh.md` for this node all carry source fingerprint `99497e3e…` while `en.md` carries `fe979666…`, so the translations were already generated from a different English revision than the one currently in the repo. That is not specific to this node: across the repo, 540 of 739 node directories that have both `en.md` and `zh.md` have mismatched fingerprints. Worth a separate look at whether the fingerprint is meant to be a staleness signal, because right now it is not being used as one.
