Add UBR (patch level) as fourth component to OS version string, and added github action build for pr (#16)

* Add UBR (patch level) as fourth component to OS version string

Reads UBR from the registry alongside productName and includes it in
the version output as major.minor.build.ubr. Defaults to 0 on older
Windows versions that do not have the UBR registry value.

* Update ChangeLog

* Potential fix for code scanning alert no. 2: Workflow does not contain permissions
