The platform labeler plugin relies on the lsb_release command to determine Linux operating system details. When the lsb_release command is not installed, it reports spurious information.

It should use additional methods to determine Linux operating system information when the lsb_release command is not available.

It currently handles Alpine Linux without an lsb_release command, but does not handle any other Linux variant without lsb_release.

Uses the /etc/os-release file which exists in many Linux implementations to indicate the operating system and its release.
