This isn't the only breaking change recently, refer below:

😅 I can't believe I forgot to make the changes I mentioned myself.
Just committed them, everything should be good to go.

other endpoints like 1k, open, /tournament might also need updating :(

I have all the tournament endpoints finished, would appreciate a double check.

There was a special case for Popular Tournaments. The data is not wrong, it is incomplete. However this appears to be intended to not take up too much space.

[
    {
        "popularity": {
            "hits": "35",
            "hitsPerDayAvg": 11.67
        },
        "tag": "...",
    },
    {}
]

The same lack of data is used in the other Popular endpoints. Might be good to complete this data, but it's not really relevant to this PR.

thank you!
