deps: bump io-uring from 0.4.0 to 0.5.0

Bumps [io-uring](https://github.com/tokio-rs/io-uring) from 0.4.0 to 0.5.0.
- [Release notes](https://github.com/tokio-rs/io-uring/releases)
- [Commits](https://github.com/tokio-rs/io-uring/commits)

The API was changed, hence some changes were needed to keep the code
building and functional.
