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.

Making node wrangler a core add-ons means that it will ship with Blender, but it still has to be enabled explicitly. It won't be available on the extensions platform anymore.
We'll still continue to move parts of its functionality out of the add-on into default Blender. However, that takes a little bit longer, because we need to go over the design and code quality in more detail first. Once, the most important functionality (#121749) is merged, the remaining node wrangler features can be put on the extensions platform.
