Support redis 4.5.x?

[Manh Luong]

1. There's a race condition bug with redis <=4.4.3 and <=4.5.3, which was addressed in the next bugfix versions.
2. I'm trying to install litestar 2.0.0alpha3, which depends on redis >=4.4.4 and >=4.5.4 (yeah they explicitly require so to avoid that race condition bug).
