chore: Update redis to 5.0.10

[jannfis]

Fixes #4748

Update redis from 5.0.8 to latest 5.0.10 patch release for both, argocd-redis and argocd-redis-ha workloads.

Also moves non-HA redis workload to alpine base image.

Superficially tested with both, HA and non-HA installations.

Can't use alpine image here, since redis binaries are not linked statically (and we copy them later on for local execution within the Docker image)
