Boolean is shown as required even though it has a default

Describe the bug When you setup a boolean field, and have other fields that are required, the boolean shows an error message even though it has a default.

To Reproduce

1. Create a boolean widget
2. Create an input widget.
3. Create a new entry, fill nothing in, click Publish.
4. Notice the UI tells you both fields are required
5. Fill in the input widget
6. Press publish
7. Notice bool still shows error
8. Turn bool on, turn bool back off
9. Press publish, notice it saves now.

Expected behavior I shouldn’t have to turn a bool from false(default), to true, to false

Ah so the default in the docs is really only used when the field isn’t required. Otherwise the default really doesn’t qualify as filled for required fields… 😃

I think just some tweaks in the docs would be fine for now.

LOL, such a simple change, but a world of difference. Thanks @erezrokah !
