🐛 Bug

Cannot import perplexity or other metrics under torchmetrics.text

To Reproduce

import torchmetrics
from torchmetrics.text import Perplexity
from torchmetrics.text.perplexity import Perplexity

None of the above imports work

• Python & PyTorch Version (e.g., 1.0): 1.12.0+cu116
• Any other relevant information such as OS (e.g., Linux): WSL

@ananyahjha93 pls see the release notes and eventually changelog, the Perplexity was not released yet, so you need to install it from source... 🐰

@ananyahjha93 just to add: basically all my time is dedicated to the classification refactor #1001.
This is the reason why many issues are basically just on hold onto that is done.
