Add "label credits" (analog to "artist credits") for label entities.

For example this release...

https://metalgodstv.com/trueheights-announce-tour-with-years-young-th15-ep-out-now%E2%80%8F/

was distributed by "Believe Digital" (in 2015) which is now rebranded as "Believe Distribution Services" since 2017.

I'd like to be able to show the name variation accordingly on the release page.
