Redis examples

Are there any examples of using redis extension?

```

org.apache.camel.quarkus
camel-quarkus-redis

```

On [page](https://camel.apache.org/components/3.11.x/others/redis.html) of component doc referring only this

`The Redis component provides an AggregationStrategy to use Redis as the backend datastore.`

Start with the Redis component documentation page linked in the issue and the shown camel-quarkus-redis dependency. Determine which Redis usage examples are missing and what documentation location should contain them. Done means the extension has concrete usage examples and the component documentation explains them clearly.
