- Set Tumbleweed appx version using same method as SLE and Leap.
* Concatenate VERSION_ID year and day of year to consume only one
segment of four segment appx version:
VERSION_ID="20210524" date --date=$VERSION_ID +"%y%j" -> 21144
* Transforming the TW version date to fit in one segment 0-65535
is necessary for compliance with the MS Store restriction that
version numbers must always increase. The two RELEASE digits
are each given their own segment for this reason.
* The kiwi generated appx file now contains both TW VERSION_ID
and the appx version for easier cross reference.
* As with SLE and Leap set digits two and three of appx VERSION
to 0 for subsequent regex or template substitution during kiwi
image build. With the zero digits e.g. 153.0.0.0 it is still
possible to manually create valid appx images for side load.
* Remove unused APPXNAME which is now set by kiwi direct appx
image creation.
