Subject: [PATCH] fix: fix comments html rendering (#5862)

Now the structure no longer has an array of author thumbnails, is a
single URL:

```json
"author": {
    "channelId": "UCiLGHgWdQvfl1G8BPgcO55w",
    "displayName": "@uber_nerd-l7r",
    "avatarThumbnailUrl": "https://yt3.ggpht.com/ee1_iFgiBvgKHUr3r0_qUVqUpGKhDZaePYq8Q4tIsyVS9L1oRHHJLcHtXrSxyS63AmvldKicbw=s88-c-k-c0x00ffffff-no-rj",
    "isVerified": false,
    "isCurrentUser": false,
    "isCreator": false,
```
