Add Plethora metadata for Item Magnets

[znepb]

I'm suggesting chat messages be sent for updates with the item magnet, such as toggle notifications, and low charge notifications. I can make a PR if this suggestion is approved.

I think a better approach would be to make sure Plethora can read magnet information (it can get the damage, but can it access Trinkets slots via getEquipment?) and then the user can set up whatever notifications they want.

Plethora can get metadata from Trinkets slots (via getMetaOwner, etc.) since https://github.com/SwitchCraftCC/Plethora-Fabric/commit/d9683ca76b863a972d5897d414ea7215fac52d0d
