(Bug 42561) Enable Ace's JSON mode

MZMcBride suggested CodeEditor should be deployed to Meta, citing the
need for a JSON-aware interface for editing articles in the new
Schema: namespace, which are JSON-encoded. The bundled distribution of
ACE supports JSON, but the extension does not include it as one of the
file formats it supports.
