Language files are missing entries for the three dimensions

en_us.json (and the other language files) are missing keys for:

• "minecraft.overworld"

• "minecraft.the_nether"

• "minecraft.the_end"

meaning that if one were to create a tooltip that had dimension-specific information, the dimension would not be translated and instead rendered using its literal translation key.

For example, imagine a datapack where players can use sticks with custom model data to teleport between dimensions.

/give @s minecraft:stick[minecraft:custom_name={"translate": "minecraft.the_end"}, minecraft:custom_model_data=...]

This item will render with the name minecraft.the_end when, by all rights, it should translate to “The End” for English-language players.
