Bumps once_cell from 1.21.3 to 1.21.4.

Changelog

Sourced from once_cell's changelog.

1.21.4

  • Fix unsoundness in OnceCell::wait under --features=parking_lot, #295.

    If thread A calls wait, while thread B calls get_or_try_init(f), and, furthermore, f panics, the wait incorrectly returns and thread A observes uninitialized memory.

    Kudos to @​meng-xu-cs for a nice find!
