Collision on enum: The type or namespace 'Date' could not be found

Describe the bug

Hello!

I am trying to generate a C# SDK for a schema that has a "date" property that can be either "date" or an enum representing "now"

However, the spec produces a compile error as neither the enum (DateEnum) or Microsoft.Kiota.Abstractions is referenced

Expected behavior

In this case, perhaps a warning should be produced for the invalid union of an enum and a date, but at the very least Microsoft.Kiota.Abstractions should be imported so that the SDK builds and is usable

How to reproduce

Generate the SDK from the following spec
