Change auto-update settings

(As per https://best-mac-tips.com/2021/10/20/disable-customise-interval-microsoft-autoupdate-macos/.)

The default auto-update interval for Microsoft Office is every two hours (7200 seconds)! To set to one week:

sudo plutil -replace StartInterval -integer 604800 /Library/LaunchAgents/com.microsoft.update.agent.plist
launchctl unload /Library/LaunchAgents/com.microsoft.update.agent.plist 
launchctl load /Library/LaunchAgents/com.microsoft.update.agent.plist

Disable completely using:

launchctl disable gui/$(id -u)/com.microsoft.update.agent

This will get reset by any updates to Microsoft AutoUpdate.
