Fix typo in 'time_series.ipynb' notebook

[tallamjr]

1. 'widow' --> 'window'

2. 'batch of 2' --> 'batch of 3'

# Stack three slices, the length of the total window:
example_window = tf.stack([np.array(train_df[:w2.total_window_size]),
                           np.array(train_df[100:100+w2.total_window_size]),
                           np.array(train_df[200:200+w2.total_window_size])])

The above snippet relating to change 2. shows three slices, implying m = 3,
i.e. 'batch of 3' instead of 2
