Required jsonnet version is buggy

[vonHartz]

As discussed here, the jsonnet version listed in requirements.txt leads to issues. I'd propose to change the requirement. Version 0.15 seems to work for me.

Hello, did you solve this problem？ jsonnet-0.15.0 seems to have the same error in https://github.com/openai/multi-agent-emergence-environments/issues/21

I double checked and jsonnet 0.15 works for me in the example I discussed in https://github.com/openai/multi-agent-emergence-environments/issues/21 . Do you get exactly the same error with the updated jsonnet?

Yes, the problem still exists after updating jsonnet, I am still trying to solve it
