[DOC] Fix typo in /clustering/_elastic_som.py

[Lucky-Lodhi2004]

Describe the issue linked to the documentation

In docstring for custom_alignment_path parameter, small typo is there. i.e.

whee the dict is the kwargs for the
distance function. See documentation of aeon.distances documentation for
example alignment path functions

should be :

where the dict is the kwargs for the
distance function. See documentation of aeon.distances for
example alignment path functions

'documentation' is also repeated.

Suggest a potential alternative/fix

The typo can be fixed appropriately

@Lucky-Lodhi2004 , thanks for pointing this out. I’d like to take this up and submit a PR to fix the typo and clean up the repeated wording in the docstring.
