Yay: Print config not human friendly

[drrlvn]

The flag --printconfig just prints the JSON in a single line with no trailing newline. It would be more helpful to pretty print it.

And it's not even a valid JSON by the way, but a print-out of the go's struct 🙂

I think the output should be exactly what cat ~/.config/yay/config.json is showing, formatted real JSON.

Printing out the go struct was the easiest and fastest way for debugging. It should be relatively easy to make it print more beautifully if someone wants to take it up, otherwise I can do it on the 24th.

@Jguer Have you worked on this yet? If not I can take a stab at it.

Sorry for the late reply @AnthonyLam , feel free to take a stab at it.
