Misdocumented embed nesting limit

[exodustx0]

From embedding.md:

Nesting is limited to two levels to prevent requesting excessive amounts of data.

https://www.speedrun.com/api/v1/games/nd2e5qed?embed=categories.game.categories.game.categories.game.categories.game.categories.game.categories only doesn't include the last Category[], i.e. the actual nesting limit is ten levels (no idea why that is in backticks).
