Have the parts of the Hadith that describe the people of Paradise as having white skin and curly hair to the point of beauty been abrogated, and what is the reason for that?

The hadith narrated uniquely by Ali ibn Zayd ibn Jud'an is weak. It is authenticated by those who consider Ibn Jud'an strong, such as Ahmad Shakir, who considers him trustworthy, and therefore authenticated its chain of narration. As for Al-Albani, he authenticated the hadith due to supporting narrations and removed the phrase "seven cubits wide" because there was no corroborating evidence for it. Al-Arna'ut authenticated it through its various chains and corroborating narrations, excluding the phrase "seven cubits wide," because Ibn Jud'an was unique in narrating it, and he is weak. Al-Hafiz Abu Hatim Al-Razi mentioned the authenticity of raising the hadith from the narration of Ibn Jud'an. It has been said that "al-ja'd" (curly hair) is a praise for the people of Paradise. As for the whiteness of their complexion, it is an indication of bliss and light, and it is the emblem of the people of Paradise.
