Setting DISCOURSE_MAXMIND_LICENSE_KEY breaks docker image/container build

Installation

Hello and welcome @cbreit :slight_smile:

I think we’ve had a couple of reports of some rebuilds failing over a Maxmind key issue:

Update from 3.0.0.beta16 to 3.1.0.beta2 - #17 by vmsman
My Discourse is Down. Certificate Issue? - #27 by JammyDodger

This may be the extra info we need to figure out what’s going on. :+1: Thanks for digging. :slight_smile:
