More automated initial items in the modulemd.yaml

[junaruga]

I was able to build on local with success for Ruby modurarity 🆗

changing from this file generated by this script
[1] https://github.com/fedora-modularity/dependency-report/blob/master/modules/ruby/ruby.yaml

to this file.
[2] https://src.fedoraproject.org/modules/ruby/blob/master/f/ruby.yaml

Look at some comments "# From" in the file [1].

I think that we can generate the items automatically from this script as the initial file.

I wish the auto-generated items by this script will be increased. :)

This is related to fedora-modularity/dependency-report#10 .

Thanks.
