Description

If a property is marked as deprecated in openapi spec, it has no effect on the generated typescript sdk. The generate model has no deprecation marker on the deprecated property. The generate model looks like:

export interface GameDto { 
    nationalLeague: boolean;
    results: boolean;
    id: number;
}

Suggest a fix

The generated model should look like this

export interface GameDto { 
    /** @deprecated */
    nationalLeague: boolean;
    results: boolean;
    id: number;
}

Start by running the typescript-angular generator with the OpenAPI declaration and reproduction command in this issue, then inspect the generated GameDto model. The work is done when a property marked deprecated in the schema emits the requested @deprecated JSDoc marker while other properties remain unchanged.
