Configmaps and Secrets in a projected volume not detected as used

[tylergmuir]

Describe the bug
Projected volumes are not checked for config maps and secrets so they get reported as potentially unused.

To Reproduce
Steps to reproduce the behavior:

1. Have a pod/deployment with a projected volume that is comprised of multiple items (configmaps and/or secrets)
2. Run popeye

Expected behavior
Since the configmaps/secrets are mapped to the pod/deployment via the projected volume, I would expect they get reported as used.

Versions (please complete the following information):

• OS: OSX
• Popeye 0.21.5
• K8s 1.27.11
