fix: replace `Print` with `Println`

[G-Rath]

This is a weird one I'm still digging into but since adding go-snaps we're getting newlines in our test output:

I've traced this down to the use of snaps.Clean and specifically this fmt.Print call - weirdly, if I replace it with this change the newline goes away but not if I do e.g. fmt.Printf(s):

I think this actually might be a bug in Go, but I'm not brave enough to try taking that on 😅

Hey 👋 Hm that's definitely weird. So why to we need the \n in Printf function? Will have a closer look just for my understanding but it looks good to me and tests are passing.
