Prepare release of 1.1.0

[githubnemo]

I took the liberty of removing the deprecated cache_net_infer context manager. The deprecation time was >1 year.

Proposed release text

Please welcome skorch 1.1.0 - a smaller release with a few fixes, a new notebook showcasing learning rate 
schedulers and mainly support for scikit-learn 1.6.0.

Full list of changes:

### Added

- Added a [notebook](https://github.com/skorch-dev/skorch/blob/master/notebooks/Learning_Rate_Scheduler.ipynb) that shows how to use Learning Rate Scheduler in skorch.(#1074)

### Changed

- All neural net classes now inherit from sklearn's [`BaseEstimator`](https://scikit-learn.org/stable/modules/generated/sklearn.base.BaseEstimator.html). This is to support compatibility with sklearn 1.6.0 and above. Classification models additionally inherit from [`ClassifierMixin`](https://scikit-learn.org/stable/modules/generated/sklearn.base.ClassifierMixin.html) and regressors from [`RegressorMixin`](https://scikit-learn.org/stable/modules/generated/sklearn.base.RegressorMixin.html). (#1078)
- When using the `ReduceLROnPlateau` learning rate scheduler, we now record the learning rate in the net history (`net.history[:, 'event_lr']` by default). It is now also possible to to step per batch, not only by epoch (#1075)
- The learning rate scheduler `.simulate()` method now supports adding step args which is useful when simulation policies such as `ReduceLROnPlateau` which expect metrics to base their schedule on. (#1077)
- Removed deprecated `skorch.callbacks.scoring.cache_net_infer` (#1088)

### Fixed

- Fix an issue with using `NeuralNetBinaryClassifier` with `torch.compile` (#1058)

Thanks, LGTM, nice find with the deprecated functions. I just have a nit to make the CHANGES.md entries consistent.

[BenjaminBossan]

Could you remove the line breaks to be consistent with the other entries? Also, the other entries are missing the PR reference, could you please add them?

Done and done

Thanks. PR is approved.
