Organize train scripts in main repo

Once we have the training scripts sorted, we should make a series of instructions for reproducibility explaining how to clone and execute the different tasks.

Since we have scripts for both the dynamical and LRA scenarios, can we close this?

[kmheckel]

Probably? I was just thinking there's a lot of .sh scripts in the top level of the repo, resulting in the README being pushed way down

Ah, that's a good point. Maybe we can move them to the experiments folder? @stevenabreu7
