version string is reported inconsistently

[nestor-custodio]

Love the new -v / --version CLI flags, but I did notice the version text is not exactly the same when you issue a caddy version (which terminates the printed version string with a newline) and when you issue a caddy -v / caddy --version (which doesn't).

This is a very minor item, but it did break my update check automation when I updated it to run --version instead of version, and I imagine it might be an issue for other (more important) tooling elsewhere.

Oh I guess it's just missing a newline? Hah 😅 I think we just need to add a \n to

caddy/cmd/cobra.go

Line 109 in 1f60328

rootCmd.SetVersionTemplate("{{.Version}}")

I'd like to make this PR if you don't mind 😄
