CheckboxOne : cannot be unchecked

[QRuhier]

Describe the bug

CheckboxOne is like a radio, but with a checkbox style and should allow to uncheck the checked modality.
Currently it does not allow to uncheck anymore

• I tested it on the storybook, which leads me to believe that it's a lunatic bug.

To Reproduce

Steps to reproduce the behavior:

1.Go to a checkboxOne component
2. Check a modality
3. Try to uncheck the modality

Expected behavior

Modality should be unchecked

[QRuhier]

Even if it's not a standard to make single-choice question modality uncheckable (since it should be radio buttons), we assume that as long as we maintain CheckboxOne this components allows to uncheck.

Then CheckboxOne works exactly like Radio, except :

• style is changed for looking like checkboxes
• you can uncheck the checked modality

@JulienCarmona @lailabent for the future, do we want to keep this component ?
