[1.20.1] Copper Buckets don't stack after holding fish or axolotls

[Blazified]

Issue

Copper buckets that have been used on fish or axolotls don't clean up their NBT and thus can't stack with unused buckets.
This causes issues with storage tech and other systems without fuzzy NBT checking.

How to reproduce

1. Pick up an Axolotl for example
2. Release the creature
3. Notice the bucket has 3 NBT tags thus causing the issue

That is a BucketLib issue that may have been fixed in later versions, I don't know.
Just in case, I have filed a bug report at cech12/BucketLib#46

The issue was already fixed in 1.20.6 and later. The upcoming BucketLib versions 1.20.1-2.3.4.3 and 1.20.4-3.2.1.5 are fixing it for Minecraft 1.20.1 and 1.20.4.
