[BUG] import ExpSmoothingSeriesTransformer and MovingAverageSeriesTransformer

[Cyril-Meyer]

Describe the bug

Working on issue #2267 with PR #2547, it looks that we cannot import ExpSmoothingSeriesTransformer and MovingAverageSeriesTransformer.

Looking at the PR implementing them (#1927 and #2019) compared with others (e.g. #1967), it seems that they are missing in aeon/transformations/series/__init__.py __all__.

Also, as I searched for doc, it seems that both class are missing in docs/api_reference/transformations.rst.

Steps/Code to reproduce the bug

from aeon.transformations.series import ExpSmoothingSeriesTransformer 

Expected results

Working without error

Actual results

from aeon.transformations.series import ExpSmoothingSeriesTransformer 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'ExpSmoothingSeriesTransformer' from 'aeon.transformations.series' ([REDACTED]\Lib\site-packages\aeon\transformations\series\__ini
t__.py). Did you mean: 'WarpingSeriesTransformer'?
from aeon.transformations.series._exp_smoothing import ExpSmoothingSeriesTransformer
