Failed to create RC k3s release

[tashima42]

The k3s release creation is failing, the error below is due to a mishandled error, but the issue is being caused by not having the owner set.

opts := &repository.CreateReleaseOpts{
			Repo:         k3sRepo,
			Name:         name,
+                       Owner:        "k3s-io",
			Prerelease:   rc,
			Branch:       r.ReleaseBranch,
			Draft:        !rc,
			ReleaseNotes: "",
		}
