Fix block entities on older versions (#756)

Browse source 
* Fix block entities on older versions

This commit solves two problems related to block entities on older versions:

- Occasionally, tags would contain the ID under a StringTag with an empty value, and not the ID tag.
- The block entity regex did not account for block entity tags that were already in a Bedrock-compatible format (BlockEntity)

* Move BLOCK_ENTITY_TRANSLATIONS to BlockEntityTranslator
