ci: add auto-generated comments to RBAC and CRD YAML files

[lokielse]

Description

This PR adds auto-generation warning comments to all RBAC YAML files and CRD YAML files to prevent manual edits. These files are generated by controller-gen and should not be manually modified.

Changes:

• Added warning comments to all RBAC YAML files in deployments/kai-scheduler/templates/rbac/
• Added warning comments to all CRD YAML files in deployments/kai-scheduler/crds/
• Updated the YAML boilerplate template in hack/boilerplate.yaml.txt

The warning comment includes:

# DO NOT EDIT - This file is auto-generated by controller-gen
# To modify RBAC permissions, edit the +kubebuilder:rbac markers in the source code
# and run 'make manifests' to regenerate this file.

This helps prevent accidental manual modifications to auto-generated files and directs contributors to the proper workflow for making changes.
