set up correct version for ci e2e job

Summary by CodeRabbit

• Tests
  • Improved kind-based testing: test setup now automatically uses the current chart version and force-reinstalls to reduce failures on repeated runs, remove manual updates to hardcoded package names, and ensure a consistent, predictable test environment—making CI and local testing more reliable and speeding up developer iteration.
