Update Redis sub-chart to >=14.0.0

Summary

Redis sub-chart included within Gitlab helm chart is out of date and not every pod and container has fully customizable securityContext values so they fail most installations when paired with basic sets of Kyverno ClusterPolicy resources.

Steps to reproduce

Deploy Gitlab chart without an external redis host configured.

Configuration used

redis:
  install: true
  metrics:
    enabled: true
  securityContext:
    runAsUser: 1001
    fsGroup: 1001
    runAsNonRoot: true
  containerSecurityContext:
    enabled: true
    runAsUser: 1001
    runAsNonRoot: true
    capabilities:
        drop:
        - ALL

Current behavior

If redis sub-chart metrics.enabled=true the metrics container within the redis master and replica pods don't have a containerSecurityContext or securityContext template available so things like runAsUser, runAsNonRoot and capabilties values to satisfy a common baseline of security recommendations for Kubernetes clusters.

Expected behavior

Every redis pod has securityContext values able to be completely set and applied.
