The developer install instruction are outdated

data/CONTRIBUTING.md

Lines 49 to 56 in 6a8415b

	### Install TorchData
	```bash
	git clone https://github.com/pytorch/data.git
	cd data
	python setup.py develop
	pip install flake8 typing mypy pytest expecttest
	```

While debugging #418 it took my quite a while to figure out that I need to set

data/tools/setup_helpers/extension.py

Line 41 in 6a8415b

_BUILD_S3 = _get_build("BUILD_S3", False)

for the C++ code to be built.

Thanks for pointing out. The documents are updated to the wrong location: https://github.com/pytorch/data/tree/main/torchdata/datapipes/iter/load#installation

Will fix it
