    - Set appx version for Microsoft Store using first segment for OS
      VERSION_ID, segments two and three for OS image release version.
      * Applies only to SLE and Leap at this time, no change to Tumbleweed
      * printf "%d.%d.%d.0" "${VERSION_ID//\./}" "${RELEASE%.*}" "${RELEASE#*.}"
      * Preserves image build versions, previous concatenation was lossy
      * Version 153.2.283.0 formerly represented as 15.3.2283.0
    - Trim os-release PRETTY_NAME to exclude snapshot or release label
      consistent with Microsoft Store registered display name.
      * PRETTY_NAME on SLE has release label in parentheses
      * Microsoft Store rejects mismatch with display name
      * Trim PRETTY_NAME from space, open paren to end of string
      * SUSE Linux Enterprise Server 15 SP3 (Snapshot 16) becomes
        SUSE Linux Enterprise Serve
