chore: update repository references to privilegedescalation org

Repository transferred from cpfarhood to privilegedescalation organization.

Updated all references in:
- Configuration files (package.json, artifacthub-pkg.yml)
- Documentation (README, CONTRIBUTING, SECURITY, docs/)
- Workflow files

GitHub Actions workflows will continue to work as they use
${{ github.repository }} which auto-updates.
