Implement HA with Sentinel

[Sir-Jacques]

Hi, we're looking for a way to run Valkey HA. Previously we used the Bitnami chart with value snippet below, to run with a sentinel StatefulSet of 3 replicas.

valkey:
  architecture: replication
  sentinel:
    enabled: true

Are there any plans for implementing this? Or can the Valkey deployment in this new chart be ran HA (zero-downtime upgrades) in a different way?

If not I might be able to setup a PR, but I'll probably need some help.
