fix readme and bundle script update

[mbpavan]

Changes

• Enhance the current README for bundle generation on Kubernetes.

• Enhance the bundle script to align with Community Operators CI requirements:

  1. config.yaml

     • Add/use min-kube-version so the bundle script can automatically set spec.minKubeVersion in the CSV.
     • This avoids manual edits and ensures compatibility with OperatorHub CI validation.

  2. bundle.py

     • Set spec.minKubeVersion using the value from config.yaml.
     • Add resource requests for operator containers:
       • lifecycle
       • cluster-operations
       • webhook
     • Set metadata.annotations.containerImage using the operator image (required for OperatorHub CI).
