Subject: [PATCH] fix more broken URLs

Tested with netlify-cli!

Note that this changes semantics, and now redirects `unstable` to the latest Nix version rather than to the most recent build from `master`.
This is to avoid
- either more downstream errors with "pretty URLs", which are not supported by Hydra
- or expensively re-building the manual on nix.dev regularly just to work around Hydra's limitations

This is probably what we want.
I assume that most people will use the latest Nix release rather than `master`.
For those who live on `master` there's still https://nix.dev/manual/nix/development, and presumably being power users they will hopefully know that.
