Related images are not included when exporting 3D datasets

[SpecLad]

Actions before raising this issue

• I searched the existing issues and did not find anything similar.
• I read/searched the docs

Steps to Reproduce

1. Create a task from the cvat/apps/engine/tests/assets/test_canvas3d.zip archive in the CVAT repository.
2. Export the task in the Datumaro 3D format.
3. Observe that the related images are missing from the resulting archive.

Expected Behavior

Related images should be included in the export result.

Possible Solution

Most likely, the problem is here:

https://github.com/opencv/cvat/blob/a5669aa1ba81c335693383015b65884794685a0d/cvat/apps/dataset_manager/bindings.py#L1462

and here:

Datumaro doesn't use the related_images parameter if the media parameter is specified. Instead of media=PointCloud(dm_image[0]), related_images=dm_image[1], it should say media=PointCloud(dm_image[0], extra_images=dm_image[1]).

Context

No response

Environment

Reproducible on app.cvat.ai.
