[BUG]: pytest and decorator required but missing in v0.3.0 requirements

[MEllis-github]

🐛 Describe the bug

Running colossalai check -i in docker.io/hpcaitech/colossalai:0.3.0 results in ModuleNotFoundError errors for pytest. With that installed, running the command results in ModuleNotFoundError errors for decorator (below). Installing decorator resolves the errors.
