fix: passing parameters to internal function call

[Peer222]

PR Description

Fixes a bug for the MultiLabelClassificationExplainer class.

Parameters passed to MultiLabelClassificationExplainer.call() are not taken into account internally (internal_batch_size, n_steps) or are passed wrongly to explainer() call (embedding_type at position of class_name).

Motivation and Context

Removing the internally created explainer (explainer = SequenceClassificationExplainer(...)) and replacing it with a super().call(...) did not work because self.attributions is then overwritten and accessing self.word_attributions fails.

Tests and Coverage

Tests still succeed. (The tests specified for the additional parameters did not catch the bug)
