Added route naming example for YAML

[ssalewski]

Description

Added the same example used for naming a route as YAML DSL

Target

• I checked that the commit is targeting the correct branch (note that Camel 3 uses camel-3.x, whereas Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally and I have committed all auto-generated changes

Thx for the contribution. Just FYI, you can inline uri with to in case you don't have other key/value pairs to provide to configure your producer, so it could be simplified with:

...
        - to: mock:bar
