Rollup merge of rust-lang#83438 - CDirkx:releases, r=Mark-Simulacrum

Update RELEASES.md

A couple of things that were missing in the release notes:

- `Div` and `Rem` by their `NonZero` variant is now implemented for all unsigned integers (rust-lang#79134)
- Stabilization of `VecDeque::range` and `VecDeque::range_mut` (rust-lang#79022, stabilization version corrected to 1.51.0 rust-lang#80448)
- Deprecation of `spin_loop_hint` (rust-lang#80966)
