Item damage event does not have an event-item value

[ShaneBeee]

Description

When using the item damage event, Skript says the event has no item stack.

Steps to Reproduce

simple code:

on item damage:
    set {_i} to event-item

results in the following error:

[15:46:45 ERROR]: [Skript] There's no item stack in an on item damage event (test.sk, line 4: set {_i} to event-item')

now the weird thing is, after writing some random code it started working.
I set up a new server, and it doesn't work on the new server. And I for the life of me cant figure out how I made it work.

Things get weirder. If I run SkriptHub's docs tool on the servers:
New Server:

      "event values": [
        "event-world",
        "event-player"
      ],

Old Server:

      "event values": [
        "event-world",
        "event-player",
        "event-itemstack"
      ],

Skript knows it exists.
This has literally got my mind baffled.

Expected Behavior

There should be an event-value

Server Information

Additional Context

I can easily fix this by adding an event-value to the code.
PR coming soon.
