support last flutter_form_builder version

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Package/Plugin version

4.4.0

### What you'd like to happen

Please update package. for support last flutter_form_builder 11.0.0

Resolving dependencies...
Because form_builder_image_picker 4.4.0 depends on flutter_form_builder ^10.3.0+1 and no versions of form_builder_image_picker match >4.4.0 <5.0.0, form_builder_image_picker ^4.4.0 requires flutter_form_builder ^10.3.0+1.
So, because campoid depends on both flutter_form_builder ^11.0.0 and form_builder_image_picker ^4.4.0, version solving failed.

You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on flutter_form_builder: flutter pub add flutter_form_builder:'^10.3.0+2'

### Aditional information

_No response_

Start with the package's flutter_form_builder dependency and current integration, then run flutter pub get using flutter_form_builder ^11.0.0. Done means form_builder_image_picker resolves with that version without dependency errors.
