fix versioned dependency in `requirements.txt`

[Kr1ss-XD]

I was trying to install katana on Archlinux, in a virtual Python en- vironment, and noticed the following.

pip install -r requirements.txt fails with the following message :

ERROR: Could not find a version that satisfies the requirement

ERROR: No matching distribution found for cmd2=='1.0.1'

This is caused by the single quotes; removing those fixes the issue.

Thanks for spotting the issue!

I added this lines to Dockerfile for temporary fix in local

RUN sed "s/cmd2=='1.0.1'/cmd2==1.0.1/g" requirements.txt > fixed_requirements.txt 
RUN pip install -r fixed_requirements.txt
