Should `sources` field be removed from `spago.dhall`?

FYI, I spotted this comment by @f-f in an old issue that came-up when working in this cookbook:

The new Spago does not have sources anymore

Don't know if this new spago is released yet. Seems like the cookbook recipes will need to updated.

It's released as spago@next, and on the way to an alpha release, at which point it is going to be the default when folks install Spago. The old Spago codebase is effectively deprecated. So I guess it is a good moment to update the cookbook - docs for the new Spago are not published yet, so it's probably best to wait for that.
