[BUG] classifiers failing on multiclass scenario due to `_get_train_probs`

The following classifiers fail on a scenario with three classes, see #6374 for the scenario:

Arsenal
BOSSEnsemble
ContractableBOSS
DrCIF
FreshPRINCE
ShapeletTransformClassifier
TemporalDictionaryEnsemble
TSCGridSearchCV - reason is not the classifier, but folds being too small in the scenario
WeightedEnsembleClassifier

A quick solution could be to introduce a capability:multiclass tag, but perhaps the bug is easy to fix.

Update: this is due to the _get_train_probs legacy method which has an undefined contract but which seems to assume a narrow range of data types (e.g., 3D numpy).
