Some of that isn't learned at all (other than through evolution). A newborn will flinch back from a growing circle on a screen.
But AI isn't an animal so the same constraints don't necessarily apply. I think you'd have to have a particularly anti-AI & pedantic bent to complain about calling this language discovery.
Feedback is fundamental to deep neural networks, it's how they're trained. And to be honest, all of the things 'astromaniak mentions can be simulated and made part of training data set too. While the "full experience" may turn necessary for building AGI, the amount of success the field had with LLMs indicates that it's not necessary for the model to learn language (or even to learn all languages).
