Flowers102 dataset does not include the class names

[ageron]

🐛 Describe the bug

Many datasets have a classes attribute containing the list of class names. I expected the same for Flowers102 but there's no such attribute:

import torchvision

dataset = torchvision.datasets.Flowers102(root="datasets", download=True)
dataset.classes  # AttributeError: 'Flowers102' object has no attribute 'classes'

I submitted PR #8838 to fix this.
