/kind bug

Description

The documentation https://docs.podman.io/en/latest/_static/api.html#operation/libpodImageTree indicates the /libpod/images/{name:.*}/tree endpoint should return a LibpodImageTreeResponse object, but the actual response is different.

Steps to reproduce the issue:

1. Query the /libpod/images/fedora/tree endpoint

Describe the results you received:

The endpoint returns:

{
    "Tree": "Image ID: 9f2a56037643\nTags:     [registry.fedoraproject.org/fedora:latest]\nSize:     182.3MB\nImage Layers\n\u2514\u2500\u2500  ID: d9e1d1e08de2 Size: 182.3MB Top Layer of: [registry.fedoraproject.org/fedora:latest]\n"
}

Describe the results you expected:

The endpoint should have returned the documented LibpodImageTreeResponse object, e.g:

{
  "id": "fedora",
  "layers": [{"..."}],
  "..."
}

@TristanCacqueray Could you open a PR to fix this?

[TristanCacqueray]

Should the documentation be changed to "string" or should the response be adapted to match the existing documentation?
