Removed feature

{
    "name": "attributeIdsAreInts",
    "description": "Update Attributes packet now has integer attribute prop ids in `key`",
    "versions": ["1.20.5", "latest"]
  },

in favor of mapping the varint to a string in protocol as we don't have an attributes data extractor (required for mapping ids=>string)
