Suggesting Edit: Install Holochain

As per holochain/holochain-rust#1760, this page needs a couple of updates IMO.

Firstly, on my computer with Manjaro Linux, I need to pipe curl https://nixos.org/nix/install with a shell command, otherwise it doesn't work (see the above issue for details). E.g., as I use zsh by default, I ran curl https://nixos.org/nix/install | zsh, other common ones would be piped with bash or sh.

Secondly, I got:

[jr@lm ~]$ nix-env --versioncopy
error: no operation specified
[jr@lm ~]$ nix-env --version
nix-env (Nix) 2.3.1

So LTM like it needs to be updated to nix-env --version.

These are fixed now
