URL: https://github.com/apache/arrow/issues/37493

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   Hello,
   
   I'm trying to sort a table on a column with dictionary type and getting the following error
   `pyarrow.lib.ArrowNotImplementedError: dictionary<values=string, indices=int32, ordered=0>`
   
   Here is a code the reproduce the error 
   ```
   import pyarrow as pa
   
   dictionary = pa.array(['a', 'b', 'c'])
   indices = pa.array([0, 1, 2, 0, 2])
   dictionary_array = pa.DictionaryArray.from_arrays(indices, dictionary)
   
   # this is working
   sorted_array = dictionary_array.sort()
   
   # this is equivalent to select specific column in a table
   chunked_dictionary_array = pa.chunked_array(dictionary_array)
   
   # this failed
   chunked_dictionary_array.sort()
   ```
   
   Thanks
   
   
   
   ### Component(s)
