What does this PR do?

Add a new E2E test to verify image build functionality using kubedock and podman when spec.devEnvironments.persistUserHome.enabled is set to true in the CheCluster.

The new test (KubedockPodmanPersistUserHomeTest.spec.ts) covers P03 scenario:

• Enables persistUserHome in CheCluster before test execution
• Creates workspace from dockerfile-hello-world sample
• Builds and pushes container image using podman with kubedock
• Runs the built container and verifies output
• Restores original persistUserHome setting after test completion
