New blocks and the Camel spawn egg are not translated.

All new blocks, such as the bamboo wood types and products, the chiseled bookshelf, the camel spawn egg and the hanging signs are all not translated.

 

Steps to reproduce:

1. Create or enter a world with experimental toggle on.
2. Acquire any bamboo wood block (planks, stairs, slabs, etc.), a chiseled bookshelf, a camel spawn egg and any hanging sign.
3. Leave the world and set the language to anything other than English.
   (I tested German, French, Italian and Hungarian)
4. Go back to your world and scroll over the items in your inventory.

Observed result:

The item names are still in English.

Expected result:

The item names are properly translated.
