Subject: [PATCH] Fixes LocalAccounts module issue in PowerShell 7

Applies a workaround for an issue where the `Microsoft.PowerShell.LocalAccounts` module fails to load in PowerShell 7 on Windows 11 23H2 and earlier.

The script now checks the OS build number and imports the module using the Windows PowerShell compatibility layer on affected systems.

Fixes: https://github.com/PowerShell/PowerShell/issues/21645
