version: prints to Stderr instead of StdOut

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).
• Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)

Commands print to Stderr instead of StdOut

Trying to fetch the version in a shell script: CI_VERSION=$(golangci-lint version --format short) I noticed the variable was empty and I could see the version printed in the terminal.
After investigating I found out that golangci-lint uses Cobra's Println function:

golangci-lint/pkg/commands/version.go

Lines 35 to 38 in c1d7cfd

	RunE: func(cmd *cobra.Command, _ []string) error {
	switch strings.ToLower(e.cfg.Version.Format) {
	case "short":
	cmd.Println(e.version)

According to Cobra, that function prints to Stderr per default:

Hi golangci-lint team,

I opened a PR fixing this issue since it is very easy to fix. Also checked all other commands and version is the only one facing this issue.
