Fixed the PowerShell syntax error in prepare-machine.ps1. The issue was using bash-style ! and 2>/dev/null instead of proper PowerShell try-catch syntax. Commit 500db4c addresses this issue.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• http://168.63.129.16:80/machine/
  • Triggering command: /usr/bin/python3 -u bin/WALinuxAgent-2.13.1.1-py3.9.egg -collect-logs (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

There is commented script in scripts/run_endpoints.sh that refers to babeltrace cmds. Should this be updated or ignored or removed?

Rest looks good to me.

Updated the commented babeltrace commands in scripts/run_endpoint.sh to support babeltrace2 with fallback to babeltrace, following the same detection pattern used in other scripts. Commit ebef950 addresses this.
