What this PR does / why we need it:

redis-stack expects configuration in file /redis-stack.conf:

if [ -f /redis-stack.conf ]; then
    CONFFILE=/redis-stack.conf
fi

However currently the ConfigMap/StatefulSet templates mount the configuration over at /redis-stack.config, so it doesn't get applied despite defining customConfig in values [1] [2] [3]:

{{- if .Values.webui.redis.customConfig }}
- name: config
  mountPath: /redis-stack.config
  subPath: redis-stack.config
{{- end }}

Testing with values.yaml:

falcosidekick:
  webui:
    redis:
      customConfig: 
        - maxmemory-policy allkeys-lfu
        - maxmemory 3000mb

And running redis-cli config get maxmemory returns no configuration, whereas it should return:

1) "maxmemory"
2) "3145728000"
