Incident 2023-06-20 - Duplicate Azure devices

@Mike Moniz,

The script will:

1. Find Resources in the ResourceGroup with the Id set in the appsettings.json.
2. Note those with a display name ending with #1 (e.g “xxx#1”) that have a “twin” (e.g. “xxx”)
3. Prompt the user to delete the duplicate (the one ending in “#1”)
4. ONLY IF the user types Capital Y” on the keyboard (deliberate safety feature for people that didn’t read the code properly!) will the device be deleted.
5. Repeat for all such devices
6. You can stop the code with Ctrl+C.
