Server software and version

CraftBukkit version 3811-Spigot-c62f4bd-85b89c3 (MC: 1.20.1)

Checks

• I am not using an outdated version of DiscordSRV.
• I asked in DiscordSRV's Discord server to see whether this issue is in fact a bug that needs to be fixed.

Anything else

This issue only affects spigot.
(correct me if I am wrong, but it is as DiscordSRV is hooking into the paper advancement api in #1502
add support for Paper advancements api for checking if advancements should be hidden

Was able to reproduce this on Paper as well
