Subject: [PATCH] fix: also fix comments community posts. (#5874)

Community posts comments still preserve the old author thumbnails
format that has an Array of thumbnails. I forgot to check that as I had
no idea `comments_youtube.cr` was also used for community posts comments

```json
"authorThumbnail": {
    "thumbnails": [
        {
            "url": "//yt3.googleusercontent.com/ytc/AIdro_m9CJFVl3bEWvGnNnN4G9ErBO2lTpKePWCjx_FQtLWaDww=s32-c-k-c0x00ffffff-no-rj-mo",
            "width": 32,
            "height": 32
        },
        {
            "url": "//yt3.googleusercontent.com/ytc/AIdro_m9CJFVl3bEWvGnNnN4G9ErBO2lTpKePWCjx_FQtLWaDww=s48-c-k-c0x00ffffff-no-rj-mo",
            "width": 48,
            "height": 48
        },
        {
            "url": "//yt3.googleusercontent.com/ytc/AIdro_m9CJFVl3bEWvGnNnN4G9ErBO2lTpKePWCjx_FQtLWaDww=s76-c-k-c0x00ffffff-no-rj-mo",
            "width": 76,
            "height": 76
        }
    ],
    "accessibility": {
        "accessibilityData": {
            "label": "SomeOrdinaryGamers"
        }
    }
},
```
