    GH-46121: [Python] Add missing `column_index` argument to 
`ArrowReaderProperties::read_dictionary`'s Cython binding (#46122)
    
    ### Rationale for this change
    This PR adds the missing `column_index` argument to 
`ArrowReaderProperties::read_dictionary`'s Cython binding to resolve the issue 
described in https://github.com/apache/arrow/issues/46121.
    
    ### What changes are included in this PR?
    1. Add the missing `column_index` argument to 
`ArrowReaderProperties::read_dictionary`'s Cython binding.
    
    ### Are these changes tested?
    No (I'm not sure where the tests for Cython bindings are; I'm happy to add 
a test if someone can point me in the right direction)
    
    ### Are there any user-facing changes?
    Yes; this is a bug fix to a user facing API (though it's admittedly 
unlikely to be used).
