Condition as an XML attribute for ForceReboot and ScheduleReboot

[valainisgt]

I believe the wix4 implementation moved conditions to attributes. However, the schedule reboot and force reboot entities were not updated to reflect this. When adding the scheduled reboot to a managed project like this:

project.ScheduleReboot = new ScheduleReboot() {
    When = When.Before,
    Step = Step.InstallServices,
    Condition = Condition.NOT_Installed & Condition.NOT_BeingRemoved
}

I get the following error when I build:

error WIX0400: The ScheduleReboot element contains illegal inner text: '( (NOT Installed)  AND  (NOT (REMOVE="ALL")) )'

Indeed it is a defect caused by the API (XML schema) changes in WiX4.
Thank you for your PR with the fix. It's merged now and will be available with te very next release.
