[DOC] Failed Example

[twobitunicorn]

Describe the issue linked to the documentation

Hi. In the "getting started" documentation here there is an example for Pipelines for aeon estimators. This example throws the following error

ValueError: Multivariate data not supported by BoxCoxTransformer

This might be an issue with either the documentation or even the transformer as it is a pd.Series being passed in so I am unsure why this error exists.

Suggest a potential alternative/fix

Either fix the documentation or it might be an error with the transformer itsef.
