chore(3p): Bump nixos-unstable channel r/1662

This bumps the channel to a commit that includes fixes for an nginx
issue we have been seeing:

https://github.com/NixOS/nixpkgs/pull/95264

Includes the following compatibility fixes:

- tests disabled in third_party.bufbuild: These were enabled
  unexpectedly by the update, but don't run in the sandbox because
  they want to download things from github
