added CatalogURL retention

[mpanighetti]

• added CatalogURL value retention for Macs running beta macOS releases (writes key back after deleting /Library/Preferences/com.apple.SoftwareUpdate.plist) #54
• differentiated variables collecting CatalogURL value from /Library/Preferences vs /Library/Managed Preferences
• added configuration profile creation instructions to README using the profile manifest hosted at ProfileManifestsMirror

So far this fix seems to be hold up and working on my Intel device, I've got 48hours left to defer before it automatically installs.

I need to try this on an Apple Silicon beta Mac too

@mpanighetti It was working on my Silicon device but Yesterday or today Apple released Monterey 12.3 beta 5 and the script detected no updates so unloaded. 1 minute later System Preferences showed the red dot and detected 12.3 beta 5

This feels like a time lag issue between clearing the update cache and "Checking for pending system updates" softwareupdate -l running

I recently changed the sleep timer to 30 before checking for pending updates, could increase back to 60 if it's a matter of needing more time for the daemon to load.

hmm I manually changed it 120....... Hopefully this is a "niche" scenario as updates on the beta channel are more frequent. I'll try again and wait for 72hours to defer for this new beta. Shouldn't get another beta release for a week or 2

@mpanighetti My Intel device powered through the transition from Beta 4 to Beta 5 with no issues (18 hours left to defer)........ Maybe this is unique to Apple Silicon?
