fix: remove extraSecrets mySecret blocking KBS deployment (#88)

The mySecret entry in extraSecrets was accidentally included in PR #85
and is preventing KBS from deploying. The trustee-operator fails every
~17 minutes with: 'Secret "mySecret" not found'

Without KBS deployment:
- No attestation service available
- All kata pods fail with CDH errors: 'Get resource failed'
- hello-openshift secure/insecure pods: CreateContainerError
- kbs-access secure pod: Init:CreateContainerError

This is a production blocker affecting all confidential workloads.

Fixes #85
