Fix: Praying mantis leaderboard

[ptlthg]

What

Praying mantis leaderboard was using the id of "praying mantis" directly in the URL, which was erroring out because there's a space in the URL. The proper url is just mantis.

Also adds support for if I change the backend api at some point to return non-sequential upcoming players which may be necessary if SkyHanni is hammering the API too much. Kinda impossible to test right now, but it seems to work.

A non sequential response might include upcoming players at ranks like:
49998, 49997, 49996, 49995, 49994, 49500, 49000, 48500
Such that there will likely be some player in the request immediately to use rather than loop with requests, we'll see if it's needed though.

If the upcoming player isn't the next one a grayed out rank shows here:
