A user was asking what to set for packaging, and I went to direct them to the guidelines/docs and realized it doesn't really explain anything atm.

Edits that have been discussed with the style lead:

Current page: Release/Packaging
Proposed update (top paragraph):

This is a list of packaging recognized by the MusicBrainz release editor.

The MusicBrainz packaging release property refers to the outermost packaging of a release, except for disposable or shipping materials. For instance, if a release consists of five jewel cases within a box, set the packaging property to 'box'.

If you have packaging that is not listed, check if another editor has already requested it in the packaging request queue. If not, then please consider requesting it.

Proposed new section (under barcode):
