Unintuitive Confirm without negative button API

[jonas-grgt]

Confirm can be used without a negative button by setting the negative display to an empty string.

This is not intuitive. I propose to add an explicit .WithNegative(false) method to make the API more explicit.

Hey @jonas-grgt , thank you so much for wanting to make this project better! I've converted this to a discussion so we can talk through it and keep our backlog clear. If it does end up being something we want to add, we'll promote it back to an issue when we are ready to work on it.
