Explain that part-of and name annotations are concatenated

Summary

The response to https://cloud-native.slack.com/archives/C017GAX90GM/p1715855191882149 expands on the following information from the Basic annotations:

And on the architectural information in How basic annotations are implemented.

DoD

Update Basic annotations and/or How basic annotations are implemented to include text such as the following:

and app.kubernetes.io/part-of or keptn.sh/app annotation to determine the name of the KeptnWorkload.
It does this by concatenating these two values:
