I know we need vuelidate update first. But we already can prepare project to migrate to Vue 3

Hey what do you think it should do for Vuelidate 2.x.

It kind of has error extraction out of the box.

I'm not seeing error extraction in Vuelidate 2.x like this provides. I think it would be useful to see this updated for Vuelidate 2.x

In Vuelidate 2 you can just use the $errors property to get the errors for each field or all of them. Let me know what you would like to see this package do.
