Wrong helm value for disable PV for prometheus alertmanager

[owenchenxy]

Describe the issue
There was a mistake in the docs about prometheus installation without PV

helm install dapr-prom prometheus-community/prometheus -n dapr-monitoring
 --set alertmanager.persistentVolume.enable=false --set pushgateway.persistentVolume.enabled=false --set server.persistentVolume.enabled=false

URL of the docs
https://docs.dapr.io/operations/monitoring/metrics/prometheus/#install-prometheus

Expected content
the value to control PV of alertmanager should be alertmanager.persistence.enabled rather than alertmanager.persistentVolume.enable

helm install dapr-prom prometheus-community/prometheus -n dapr-monitoring
 --set alertmanager.persistence.enabled=false --set pushgateway.persistentVolume.enabled=false --set server.persistentVolume.enabled=false
