[BUG] TBATS docstring example does not run

[josebaezmedina]

The example for TBATS from the documentation does not work.

from sktime.datasets import load_airline
from sktime.forecasting.tbats import TBATS
y = load_airline()
forecaster = TBATS(  
    use_box_cox=False,
    use_trend=False,
    use_damped_trend=False,
    sp=12,
    use_arma_errors=False,
    n_jobs=1)
forecaster.fit(y)  
y_pred = forecaster.predict(fh=[1,2,3])  

Expected behavior
predictions from the time series

I am getting:
TypeError: _TbatsAdapter.init() got an unexpected keyword argument 'seasonal_periods'

Thanks for reporting.
Could you kindly list your package versions, as described in the "new issue" template?

I've also added a test with sp parameter to see if something comes up there:
#6292

@josebaezmedina, the tests in #6292 seem to run with the example above.

Possibly it is an issue with incompatible package versions in your environment?

Would appreciate package versions.
