Fix beacons in folia

[Goosius1]

Description:

• With current code it looks like Folia doesn't like a "block.getType()" call in siegewar which is triggered by an event listener.
• This was the report I got from a server owner:

[16:10:03 ERROR]: Could not pass event NewShortTimeEvent to SiegeWar v2.7.0
java.lang.NullPointerException: Cannot read field "captureTreeGeneration" because the return value of "net.minecraft.world.level.World.getCurrentWorldDa
ta()" is null

• I believe this PR should fix it, but putting the getType call onto a scheduler.
• I don't have Folia myself so I can't fully test this now, but its a small change so maybe someone with Folia knowledge can just confirm if it will fix the issue
