Describe the bug

If an input of a flake which has flake = false; is modified to remove this, the lockfile isn't updated to match by nix flake lock.

Steps To Reproduce

#!/usr/bin/env bash
set -exuo pipefail

! [[ -e test-flake-lock-flake-attr-change ]] || rm -r test-flake-lock-flake-attr-change
mkdir test-flake-lock-flake-attr-change
cd test-flake-lock-flake-attr-change

cat > flake.nix <<EOF
{
  inputs.systems = {
    url = "github:nix-systems/nix-systems";
    flake = false;
  };
  outputs = _: {};
}
EOF

nix flake lock
cp flake.lock flake.lock.before
sed -i '/flake = false/d' flake.nix
nix flake lock
if diff flake.lock{,.before} ; then
	echo "fail"
	exit 1
fi

Expected behavior

The new flake.lock should differ from the old one, to reflect that b is no longer flake = false;.

`nix --version` output

nix (Lix, like Nix) 2.92.0-dev-pre20241111-8a90943
