Fixing crash due to old dependency. And also bugfix for training objectives.

xgb | Classification | 🔴 | Crashes (iteration_indptr needs XGBoost ≥ 2.0, 1.7.5 is pinned). Even with that fixed, it trains a regression objective.

It also adds a mechanism for simple learning rate scaling based on number of clients in the federation. This makes the training robust to federations of different sizes.

The next step would be to also add option for scaling based on the client size.
