Roadmap for moving vz out of experimental

[AkihiroSuda]

• Basic tests CI: add vz #1511
• CI: vz: enable systemd-strict and port-fowards tests #1611
• [kernel v6.2 regression, affects Ubuntu 23.04 and Fedora 38] limactl start --set '.vmType = "vz"' crashes: "usernet unable to resolve IP for SSH forwarding" #1577
• Experiencing slow network under VZ virtualization #1333
• vz: lima managed vm hangs with high CPU usage intermittently. #1609
• VM disk corruption with Apple Silicon #1957
  We can also consider making vz default after moving it out of experimental

This issue seems also significant although it is hard to reproduce and root cause.

• Use VZ by default for new instances on macOS >= 13.5 #1951
