SQL Server Jobs - syspolicy_purge_history fails
Thanks to the comment of @Tony Hinkle.  I was able to resolve the issue based on the comment at the bottom of this thread.

SQL Server 2012 syspolicy_purge_history fails step 3 "Erase Phantom System Health Records."

Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.SqlServer.Management.PowerShell.sqlps130 I changed the key ExecutionPolicy value to Unrestricted.

I did not make any changes to keys under HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\PowerShell\1\ShellIds\Microsoft.SqlServer.Management.PowerShell.sqltoolsps130.
