Widgets should not fake present a default value

Take the Image Block for example.
You have the generation of sizes gives certain options enabled
https://github.com/plone/volto/blob/main/packages/volto/src/components/manage/Blocks/Image/View.jsx#L70
https://github.com/plone/volto/blob/main/packages/volto/src/components/manage/Blocks/Image/utils.js#L13
When you add an image you see selected 2 options
The L size
and the Center align
That selection is fake actually because they are added as missing value defaults.

Since we store widget options within the data object, the data is empty and any code that checks for it will not find it.

The solution for instance to get the value "l" present in the data is to add here
https://github.com/plone/volto/blob/main/packages/volto/src/components/manage/Blocks/Image/schema.js#L83
default: 'l'.

Doing so the image size is set correctly and it shows up in the data as seen in this screenshot where I had default value 'm' to ensure that there is no fallback value selected:

EDIT:
Unless there is a widget value added to the data object which happens when you set a default in the schema, the sizes will return undefined which judging by the looks of the options selected it should have selected sizes: "100vw".

@sneridagh have a look when you have time to the comment I left above

Line 83 in b1797b4

widget: 'image_size',

this should have a default value of "l"
