bb2667ca - Error on `--locked` and `--frozen` when script lockfile is missing (#18832)

Error on `--locked` and `--frozen` when script lockfile is missing (#18832) However, we do not error when these are set as environment variables for backwards compatibility and general safety since those variables could only be intended for project use.
