[BUG][Typescript] Invalid oneOf strategy in models

Description

Typescript generator generates new model for oneOf PublicActionDefinitionInputFieldDependenciesInner. It impossible to send proper request to API using this model. PublicActionDefinitionInputFieldDependenciesInner model doesn't contain a field for choosing oneOf's models. The generator version 5.4.0 uses union types: PublicSingleFieldDependency | PublicConditionalSingleFieldDependency. Can I create a PR for returning back to union types? Can I create sample app for testing it?

Output

export class PublicActionDefinition {
    'inputFieldDependencies'?: Array<PublicActionDefinitionInputFieldDependenciesInner>;
}

PublicActionDefinitionInputFieldDependenciesInner model:


import { PublicConditionalSingleFieldDependency } from './publicConditionalSingleFieldDependency';
import { PublicSingleFieldDependency } from './publicSingleFieldDependency';

export class PublicActionDefinitionInputFieldDependenciesInner {
    'dependencyType': PublicActionDefinitionInputFieldDependenciesInner.DependencyTypeEnum = PublicActionDefinitionInputFieldDependenciesInner.DependencyTypeEnum.ConditionalSingleField;
    'dependentFieldNames': Array<string>;
    'controllingFieldName': string;
    'controllingFieldValue': string;
    static discriminator: string | undefined = undefined;

...
}

export namespace PublicActionDefinitionInputFieldDependenciesInner {
    export enum DependencyTypeEnum {
        ConditionalSingleField = <any> 'CONDITIONAL_SINGLE_FIELD'
    }
}
