Add MusicBrainz link to ‘Socials’

[Aerozol]

Add the MusicBrainz link to ‘Socials’ - although it is down by ‘submit corrections’, for a hot second I couldn’t find the MB link. This would be consistent with the ‘other databases’ links there already.

Disclaimer: I work part-time for the MetaBrainz foundation - I see this tool pop up a lot on my Reddit alerts :)
Feel free to decline the change, of course!
