Before, providers were only built indirectly. Since proviers don't depend on terraform to build they can be moved into their own collection of packages. This also has the advantage that they can be reached directly using an attribute path (Eg: terraform-providers.nixos). Co-authored-by: Wael Nasreddine <wael.nasreddine@gmail.com>
