Showing default values next to checkboxes

[Producdevity]

First of all, I want to thank you for this handy library!

When I was using it I thought that it might be intuitive to show the default values when letting the user decide which properties they want in the generated .prettierrc next to the checkboxes.

If this is to much work for you I'm willing to help (with a PR). Just let me know if this is something that's in the scope of this project

@YassineGherbi let me check if I have time to implement that, otherwise if you want to PR it, just go for it.
