Fix k3d dev script

General MR

Summary

• Make Twistlock k3d node mounts opt-in
  Avoid mounting the host /etc into k3d nodes by default, since it can break Docker archive reads of /etc/hosts during k3d cluster creation. Add an explicit --enable-twistlock-node-mounts flag for Twistlock defender testing that still needs the legacy host mounts.

This script likely started failing with new Docker https://docs.docker.com/engine/release-notes/29/#2951 release to combat some docker cp CVEs
