Subject: [PATCH] fix: skip non comment `commentFilterContextViewModel` key in
 comments (#5870)

Some YouTube videos like https://www.youtube.com/watch?v=Ajkr_Wg-k8g
had an non comment key that was inside the Array that contained some
comment information that Invidious parses (like comment_key and
toolbar_key), that being the `commentFilterContextViewModel` key, which
is just an indicator on how comments are sorted:

```
{
    "commentThreadRenderer": { ... } <- comment information that is
    handled by line 134 of youtube.cr
},
{
    "commentFilterContextViewModel": {
        "text": {
            "content": "Top is selected, so you'll see featured comments"
        },
        "accessibility": {
            "accessibilityData": {
                "label": "Top is selected, so you'll see featured comments"
            }
        }
    } <- Useless information, this is not a comment
}
```
