Missing dependence in requirement.txt of applications/DeepSpeed-VisualChat

We should add tensorboard to the requirement.txt, the moniter of deepspeed require it.

ModuleNotFoundError: No module named 'tensorboard'

Open applications/DeepSpeed-VisualChat/requirement.txt and compare it with the dependency used by training/main.py. Add tensorboard, then run the training entry point through DeepSpeed initialization and confirm the missing-module error no longer occurs.
