ARROW-17274: [GO] Remove panic from parquet.file.RowGroupReader.Column(index int) (#13767)

Remove panic from `parquet.file.RowGroupReader.Column(index int)`

- parquet.file.RowGroupReader.Column(index int) panics if the the provided column index is invalid.
- Return an error as the rest of the functions in the codebase return an error as well.  For example GetColumnPageReader returns (PageReader, error) 
- fixed usage in tests
