The bl_info dictionary is deprecated for most extensions, but it is
still used for core add-ons and since Node Wrangler is now built-in,
it should be marked as official.
The reason for this change is actually that it enables translation of
the Node Wrangler UI, because add-ons below official support level
were never considered for translation.
-----
The reason only OFFICIAL add-ons are translated is that they are enabled [here](4f36fb1afe/scripts/modules/bl_i18n_utils/bl_extract_messages.py (L1052)) during message extraction.
