Feat: Add an acknowledge checkbox

[MuscularSloth]

Hey, @jonatanklosko!

I have a feature that adds an acknowledge checkbox if it's needed. Until this checkbox is unchecked the confirm button will be disabled. Additionally you can set the custom label, custom form control props and custom checkbox props.

Also I've prepared all tests for it and ready to create a PR. How can I do it?

@MuscularSloth sounds good, feel free to open a PR :)

How can I do it?

Fork this repo, create a branch with your changes, push the branch to your fork and open a PR from that. If anything is not clear let me know.
