🚀 Deprecation of TorchText releases

As of September 2023 we have paused active development of TorchText because our focus has shifted away from building out this library offering.

We would like to do the following:

• For TorchText Release 0.17.2 and 0.18.x TorchData dependency is removed from TorchText [COMPLETED]
  • Users can still install torchdata manually to use the datasets
• Minor PyTorch Release 2.3 will be last Release where we release TorchText 0.18
• Starting PyTorch Release 2.4 we would like to stop releasing TorchText.
• TorchText will still be available from nightlies on a best effort basis, with no guarantee that we'll be fixing issues and breakages

For reference here is the PyTorch Release schedule:
