Review comment:
`Series.set_axis` is the same as `DataFrame.set_axis` with `axis=index`
(since there are no column names to assign). So this method should always raise
like the latter.

> Implement set_axis for DataFrame and Series
> -------------------------------------------
>
> Key: BEAM-12566
> URL: https://issues.apache.org/jira/browse/BEAM-12566
> Project: Beam
> Issue Type: Improvement
> Components: dsl-dataframe
> Reporter: Brian Hulette
> Assignee: Benjamin Gonzalez
> Priority: P3
> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> Add an implementation of
> [set_axis|https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.set_axis.html]
> for DeferredDataFrame and DeferredSeries. It should be fully unit tested
> with some combination of pandas_doctests_test.py and frames_test.py.
> https://github.com/apache/beam/pull/14274 is an example of a typical PR that
> adds new operations. See
> https://lists.apache.org/thread.html/r8ffe96d756054610dfdb4e849ffc6a741e826d15ba7e5bdeee1b4266%40%3Cdev.beam.apache.org%3E
> for background on the DataFrame API.
