Add SystemSettingsAdminFlow.exe as a LOLBin

[JasonPhang98]

This pull request adds SystemSettingsAdminFlow.exe as a new entry to the LOLBAS project under the OSBinaries category.

SystemSettingsAdminFlow.exe is a legitimate Windows executable used to handle administrative flows in system settings. However, it can be abused to modify critical Windows Defender settings, such as disabling enhanced notifications, submission consent, and real-time protection, allowing for execution of malicious payloads without detection.

The included YAML file demonstrates commands that attackers could use to manipulate Defender settings.
This activity maps to T1562.001 (Impair Defenses: Disable or Modify Tools).
