Bug
What is the current behavior?
Date in interface and schema are not compatible for Date.
If the current behavior is a bug, please provide the steps to reproduce.

interface Something {
    field: Date;
}
const someSchema = new Schema<Something, Model<Something>, Something>({
    field: {type: Date}
})

error:
Types of property 'type' are incompatible.
Type 'DateConstructor' is not assignable to type 'Date | typeof SchemaType | Schema<any, any, undefined, unknown> | undefined'.
Type 'DateConstructor' is missing the following properties from type 'typeof SchemaType': cast, checkRequired, set, get.

However if using field: {type: Date} as unknown as Date it works.
