[FIX] website: display correct value on website_publish_button

Following the refactor done in [1], it is no longer possible to use the
`value` prop. Instead, the field should explicitly use
`props.record.data[props.name]`.

However, while [1] tried to adapt all the existing fields,
`website_publish_button` was forgotten.

This commit adapts website_publish_button.

Steps to reproduce:
- Install website_sale
- Go to the website app
- In the configuration menu select Shipping Methods
- Chose one of the shipping method
- Try to toggle the "Unpublished/Published" button
=> The value does not update properly
