Subject: [PATCH] fix: fix `Missing hash key: "collectionThumbnailViewModel"`
 for channel video thumbnails (#5725)

Now the Innertube structure doesn't include `collectionThumbnailViewModel`
and `primaryThumbnail` keys.

Now the structure looks like this:
```
"horizontalListRenderer": {
    "items": [
        {
            "lockupViewModel": {
                "contentImage": {
                    "thumbnailViewModel": {
                        "image": {
                            "sources": []
...
```
