Docker installation with data softlink bug fixed?

Hi there,

I found that in current ReadMe file local evaluation step 5, if a soft link is used and the suggested docker command is run, there would be an error message like this:

 2021-04-13 21:51:15,680 Initializing dataset ObjectNav-v1
 2021-04-13 21:51:15,710 initializing sim Sim-v0
 WARNING: Logging before InitGoogleLogging() is written to STDERR
 E0413 21:51:15.723701    17 StageAttributesManager.cpp:90] StageAttributesManager::registerObjectFinalize : Render asset template handle : habitat-challenge-data/data/scene_datasets/mp3d/x8F5xyUWy9e/x8F5xyUWy9e.glb specified in stage template with handle : habitat-challenge-data/data/scene_datasets/mp3d/x8F5xyUWy9e/x8F5xyUWy9e.glb does not correspond to any existing file or primitive render asset.  Aborting. 
  submission.sh: line 3:    17 Segmentation fault      (core dumped) python agent.py --evaluation $AGENT_EVALUATION_TYPE $@`

My fix was to change this line:

 -v $(realpath habitat-challenge-data/data/scene_datasets/mp3d) \

to

  -v $(realpath habitat-challenge-data/data/scene_datasets/mp3d):/habitat-challenge-data/data/scene_datasets/mp3d \

Not that familiar with Docker, so not sure whether this is a version problem or a bug. Just want to post one solution!

Best, Yiqing

@erikwijmans By the way, there is still a small problem in the readme. The path is no longer working, it should be /habitat_baselines/config/objectnav/ddppo_objectnav.yaml(If the script runs under the habita-lab folder).

Likely a versioning thing as -v $(realpath habitat-challenge-data/data/scene_datasets/mp3d) \ worked at the time, but your update seems more portable! I will update the readme
