[dependabot]

Updates the requirements on redis to permit the latest version.

Release notes

Sourced from redis's releases.

v0.22.0

Redis-rs is a high level redis library for Rust and aims to provide convenient access to all Redis functionality through a very flexible but low-level API. The crate has recently come under maintainership by @​djc and @​jaymell. Much appreciation and many thanks to @​mitsuhiko, @​badboy, @​Marwes for their work in building this library over the years! The new maintainers hope to improve the velocity of bug fixes, new features, and PR reviews in the coming months.

This release adds various incremental improvements, including additional convenience commands, improved Cluster APIs, and various other bug fixes/library improvements.

Although the changes here are incremental, this is a major release due to the breaking changes listed below.

This release would not be possible without our many wonderful contributors -- thank you!
