Subject: [PATCH] Be more tolerant of invalid attributes
Prior to this commit, the player would be disconnected if they ever encountered an attribute with a name that did
not match Bukkit's expected vanilla scheme. It appears that datapacks can set whatever attribute name they want,
ignoring vanilla's typical scheme.
In a more perfect world the API would expose some way to interact with these attributes, however Bukkit is not
particularly flexible in this area. Perhaps this is an area for future expansion at a later time.
