This PR reduces the creation of short-lived basic_json objects while parsing flake.lock files. For large flake.lock files (~1.5MB) I was observing ~60s being spent for trivial nix build operations while after this change it is now taking ~1.6s. (cherry picked from commit 7fd0de3) (cherry picked from commit f94fb63)
