fix: golang printf lint error

[minniux]

This is a small change, mainly switching fmt.printf with fmt.print to fix the following:

While building a new docker image for Stride, the lint step is failing as printf is specified without formatting

P.S. In the GH actions output there are no enough details, but running the lint locally makes it clear:

docker/docker.go:74:15: printf: non-constant format string in call to fmt.Printf (govet)
			fmt.Printf(dockerLogLine.Stream)
