Add a method on InventoryView to get the MenuType

[GliczDev]

It is possible to get the InventoryType, but not MenuType.
Since there is a new (better) way to create views for players using MenuType, it would be nice to also be able to get it back from InventoryView after creating.

In order to ensure the API functions properly, some adjustments are needed. I’ve tested it, and currently, the API throws an error for any menu that doesn’t have a MenuType. This is an issue in scenarios like the player’s inventory or with animals, where a MenuType is not applicable. In these cases, it results in an UnsupportedOperationException. If you’re aiming for this to be merged, I’d recommend modifying the behavior to return null instead of throwing the exception. Otherwise, everything else seems fine. I'm not in love with the CraftContainer impl, but I think its pretty much unavoidable at this point sadly.

In these cases, it results in an UnsupportedOperationException.

@Y2Kwastaken does it also throw in CraftContainer implementation? It seems that CraftContainer.getNotchInventoryType never returns null, so there should be no issues, but I want to verify it.

The naive conversion for Inventory's is fine and won't throw that exception to see why its thrown see AbstractContainerMenu#getType. This goes back to what I explained earlier where not every Menu has a MenuType sadly.

This is a lot better thank you, From my testing it works as you'd expect.
