[BUG] Schema Fetch Failure in Compiler Due to Certain DDL Operations in Groot

[BingqingLyu]

Describe the bug

As titled. This issue is triggered by specific data types, such as float, used in the DDL operations.

e.g., when creating new vertex or edge types with properties of datatype float, the compiler output error logs as follows:

The reason is that, in https://github.com/alibaba/GraphScope/blob/main/interactive_engine/common/src/main/java/com/alibaba/graphscope/groot/common/util/IrSchemaParser.java#L126
we didn't convert DataType like Float. This is related to the data type refactor issue #4362 .
