Chef::Cookbook::Metadata#gem_requirements_to_array

Convert an Array of Gem::Dependency objects (chef_version/ohai_version) to an Array.

Gem::Dependencey#to_s is not useful, and there is no #to_json defined on it or its component
objets, so we have to write our own rendering method.

[ Gem::Dependency.new(">= 12.5"), Gem::Dependency.new(">= 11.18.0", "< 12.0") ]

results in:

[ [ ">= 12.5" ], [ ">= 11.18.0", "< 12.0" ] ]
