Description

When registering blocks from PHP, either by using register_block_type or wp_register_block_types_from_metadata_collection, they use under the hood register_block_type_from_metadata. This function in turn attempts to load translations from plugin root. It is much more common, and would be a good practice to offer a choice from where it should be loaded, and that is typically /languages folder.

Step-by-step reproduction instructions

Use register_block_type or wp_register_block_types_from_metadata_collection to register a block(s).
Create some translations for block.json metadata like block title etc. Use query monitor plugin to debug and see from where is loading of translations attempted.
