Should prettier be a hard requirement?

[antoniolibrada]

Hello !

I have been trying your script and I have gotten an error saying that I needed to install prettier. Can you state that as a dependency or in the documentation?

I will probably do it afterwards if I get time.

Thanks :)

I have seen, it is a peer dependency... Silly me

Actually maybe it shouldn't be? It's cool to format with prettier if we have it, but force us to install it just for the script is bit much, don't you think?

Thanks.

This is an example why prettier shouldn't be required: https://github.com/valtech-ch/ring/runs/2858342339?check_suite_focus=true

I need to install prettier and delay the action more than minute

it would be nice to have a parameter to disable it. Do you accept a PR for it?
