Docs: Lazy/Schemas/Type checking: Polars does not raise when calling round(0) on an Int64 column

[mlondschien]

Description

The example in https://docs.pola.rs/user-guide/lazy/schemas/#type-checking-in-the-lazy-api does not behave as expected. Polars does not raise when calling round(0) on an Int64 column.

The behavior is intended (#17241) but the user guide should be updated.

@rodrigogiraoserrao can you take a look?
