Feature request: add os.kernel.version semantic convention

[povilasv]

👋 I'm working on k8s cluster receiver on the collector-contrib repo and we would like to propose adding os.kernel.version as resource attribute.

Currently Kubernetes exposes this in Node status field. Additionally, it can be found on Linux using uname -r , and windows seems to also have notion of kernel version. Reference: https://superuser.com/questions/296020/windows-kernel-name-version
