I don't think we're going to need this because I removed once_cell usage in #13991 because it's not needed anymore after that. Although I'm not going to close this yet, because we might have a transitive dependency on once_cell and if so we probably want to bump the version in the lock file still.

Cool dependabot detected we removed once_cell from Cargo.toml and handled it correctly.
