Description

Currently if no value for y is passed to the TimeSeriesImputer, the resulting output returns a pd.Series object with one None value due to this.

The behaviour should match our other components and y should be returned as None if nothing has been passed in.

Contributor guide

Research direction
Modify the return statement in the TimeSeriesImputer to return None instead of a pd.Series with None when y is not provided, aligning with other components.
