Fixes #5883

• to run unit/integration tests, the developers should use runtests.sh
  which implements
  

  MONAI/runtests.sh

  Lines 130 to 133 in 2d0e021

  	function install_deps {
  	echo "Pip installing MONAI development dependencies and compile MONAI cpp extensions..."
  	${cmdPrefix}${PY_EXE} -m pip install -r requirements-dev.txt
  	}

• for read-the-docs builds, it automatically runs cd docs; make html:
  which installs docs/requirements.txt
  

  MONAI/docs/Makefile

  Lines 22 to 23 in 2d0e021

  	%: Makefile
  	PIP_ROOT_USER_ACTION=ignore pip install -r requirements.txt

the docs/requirements.txt is only for building the docs, and should work with a tiny workstation instance
