pin some dependencies (there were some compatibility issues with most recent versions of some libraries);
add runs/.gitignore to git tracking (so that we don't have to be careful with that every commit);
add local run to PPO training (I took the freedom to do that not in the most elegant way, but the only way I thought of that wouldn't require commenting code would probably mess with other scripts/methods as well, so I'm avoiding this for now)
Training can be run now! No idea if it's behaving correctly, but it's better than getting errors.
