Subject: [PATCH] ci: use nix copy instead of nix-copy-closure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Also use `ssh-ng://` protocol implementation instead of `ssh://`.
Might fix the following error:
```
error (ignored): error: reached end of FramedSource
error: sized: unexpected end-of-file
error: unexpected end-of-file
```
For more details see: https://github.com/NixOS/nix/issues/6495
