doc: A pubsub component allows consumerID to set "{podName}" and "{namespace}"

[TonyPythoneer]

Describe the issue

This page only mentions that consumerID can be set to a string value but doesn't mention other possibilities, such as "{podName}" and {namespace}".

URL of the docs

https://docs.dapr.io/reference/components-reference/supported-pubsub/setup-redis-pubsub/

Expected content

For example:

consumerID  N   The consumer group ID   *string value: "myGroup"  * string format value: "{podName}", "{namespace}", or else

---

Additional context

When I digged other pages, I noticed the following:

• https://docs.dapr.io/developing-applications/building-blocks/pubsub/howto-subscribe-statefulset/
  • consumerID can be set to "{podName}"
• https://docs.dapr.io/developing-applications/building-blocks/pubsub/howto-namespace/
  • consumerID can be set to "{namespace}"

Could the team clarify all the possibilities on the page for all the pub-sub components? https://docs.dapr.io/reference/components-reference/supported-pubsub
