Undefined variable $extra_fields in aiprompt_content_entity_extra_field_info()

The patch attached fixes the issue of undefined variable.

@ayush.pandey, I have fixed the issue, please review MR

This line is too much info, because it is self evident that variable is being initialized.

// Initialize $extra_fields as an empty array.

Attaching patch with removing comment.
