SingleData.to_series() passed a qlib Index object directly to pd.Series(), which raises TypeError since pandas does not recognize it as a valid index type. Use .tolist() to convert to a plain list first, consistent with how __repr__ already handles it on line 618. Fixes microsoft#2020

The
Indexclass inqlib/utils/index_data.pyis a custom high-performance index wrapper. While it supports iteration and.tolist(), pandaspd.Series()constructor does not accept it as a validindexparameter. The__repr__method (line 618) already uses.tolist()correctly, butto_series()(line 614) did not.Test plan
