Subject: [PATCH] build: use top-level fetchPnpmDeps/pnpmConfigHook +
 fetcherVersion=2

Nixpkgs deprecated pkgs.pnpm.{fetchDeps,configHook} in favor of the
top-level pkgs.fetchPnpmDeps and pkgs.pnpmConfigHook. fetchPnpmDeps now
requires fetcherVersion to be set; 2 is correct for pnpm v9+ lockfiles.
