"nix-store --init" is not documented in the man page or --help text

[ghost]

Describe the bug

The manual page for nix-store does not mention "nix-store --init"

Steps To Reproduce

1. Wonder "gee, how do I initialize an empty nix store?"
2. Check the man page. Nothing there.
3. Try "nix-store --help". Nothing there.
4. Try the nix manual. Nothing there.
5. Try web search engines. Become frustrated with the non-uniquenss of the word "nix". Become even more frustrated with Google trying to spell-correct "nix" into "unix". Abandon all hope for the future of the web.

Expected behavior

Somebody adds a one-line mention of "nix-store --init" to the documentation for nix-store.

As far as I know, nix-store --init is useless now, and only here for backwards-compatibility as stores will be created on-the-fly as needed

This isn't true if you specify store = in nix.conf. The store needs to be created before the daemon in that case.
