Generated structure IDs are not resource locations; no namespace and not lowercase

Recently, entity IDs were changed to make them consistent with block and item IDs. Then the /locate command was added and it has the same ID format as the entity IDs did before they were changed to make them consistent.

For example:

• /locate Village

Compare with

• /give @p minecraft:wooden_door
• /summon minecraft:villager

IMAGES:
/locate vs /summon and /give

They are also case sensitive.
