Preconditions and environment

• Magento version: 2.4.7-p9 (2.4.*)

Steps to reproduce

• Use API endpoint /rest/all/V1/products
• repare payload to define configurable options
• Since we can't omit the "label", we set "is_use_default": true along side of a generic label.

Expected result

• the use_default field in catalog_product_super_attribute_label is set to 1 for the updated option
• The PDP shows the default attribute label as configured in attribute settings

Actual result

• is_use_default flag is being ignored in API and does not translate to use_default field in DB
• The required "label" field set in API payload is always used as custom option label
