Closes #39669

• Certain attributes, like the email, might only be updated through an AIA. In this case, the UP configuration will allow setting a "annotation decorator" to dynamically resolve annotations based on contextual data so that UIs can check whether or not a link to initiate the action should be rendered.
• The reason why this issue is resolved using an annotation is because the attribute is indeed readonly when at the ACCOUNT context, and we can not rely on the org.keycloak.representations.idm.UserProfileAttributeMetadata#readOnly field to decide to show or hide the link. In addition to that, annotations serve as a hint to UIs about how to render attributes.
