Fix nil bug when there's no dependency key in package.json

[koddsson]

I just have devDependencies in my project and I'm getting this error:

Users/koddsson/src/koddsson/console/vendor/bundle/ruby/3.4.0/gems/licensed-5.0.1/lib/licensed/sources/npm.rb:68:in 'Licensed::Sources::NPM#recursive_dependencies': undefined method 'each' for nil (NoMethodError)

        dependencies.each do |name, dependency|

This patch should fix it by defaulting to a empty hash if dependencies is nil.
