feat(nix): Default to release build

[NickLarsenNZ]

This doesn't necessarily fix #385, but it does stop the crash (as tested).

Default nix builds to the release profile.

It can be disabled like so:

stackablectl = (import
    (pkgs.fetchFromGitHub {
      owner = "stackabletech";
      repo = "stackable-cockpit";
      rev = "stackablectl-1.0.x";
      hash = "...";
    })
    # 👇 see here
    { release = true; }).cargo.workspaceMembers.stackablectl.build.override;

Not really a fix to the issue at hand, but LGTM besides that.
