Add TorchData as a required dependency in TorchText for 0.13.0 release

[Nayef211]

🚀 Feature

TorchData is currently an optional dependency which means users have to pip install torchdata if they want to be able to use our datasets. Since datasets are a core feature of TorchText, we want to improve the user experience by making TorchData a required dependency.

After the next torch and torchdata branch cuts for version 1.12, we want to take a hard dependency on the torchdata nightlies.

@atalman @malfet @seemethere @ejguan do you guys know if we have the go ahead to make TorchData as a required dep moving forward? I know we were aiming to do this with the last release but it got pushed back to the 0.13 release instead.

Yeah, it would be great if we TorchData are aware of the requirements/criteria to make this happen. Then, we can investigate if we have any step missing.

After #1979 is fixed, could we start to make torchdata as a hard dependency in the main branch? Then, we will be able to spend time on figuring out what's wrong with the installation script.
