Subject: [PATCH] Update towards-reproducibility-pinning-nixpkgs.md (#1029)

I expected the `<nixpkgs>` link to point to a resource that explains what that construct is and not directly to Nixpkgs. If I would be totally new to Nix, that would be even more confusing.

 This is a **convenient** way to quickly demonstrate a Nix expression and get it working by importing Nix packages.
 
 However, <ref-search-path>**the resulting Nix expression is not fully reproducible**.
