[BUG] Bug in data type conversion that causes subgraph() to fail in CI

[BingqingLyu]

Describe the bug

As titled.

In ir-core, there are bugs in converting data types to the new data type definition, resulting in empty data types in the schema. The subgraph() function relies on this schema defined in ir-core, which causes related CI tests to fail, e.g.,:
The failed ci: https://github.com/alibaba/GraphScope/actions/runs/12739264127/job/35502923024?pr=4310

Fix this.
