MLP rib build -> ablation pipeline is broken.

[nix-apollo]

This change is breaking for run_mlp_ablations, as run_mlp_ablations expects to find mlp config information at results["model_config"]["model"]. Instead mlp rib build now stores only the mlp config info, omitting mlp training config, etc.

[nix-apollo]

Probable change is to go back to storing training information, etc in rib results. But I'm unsure what's best for consistency with modular mlp and eventually combining ablation scripts

Yeah I think I'd like to have all train information stored in the results. I'm going to work on this now and make a PR to main, since I'd like to have this in the refactor.

OK I decided against this to keep things consistent with lms. Otherwise it's a bit messier.
