rke2: update and release packages by official release channels (#315599)

Get the legal go version from the k8s project.

Use the `buildGoModule` compilation package instead of patching the build script.

Add documents to explain Release Channels and support strategies.

Increase the metadata `eol` (End of Life) to mark the life cycle of the package.
