[BUG][typescript-fetch] "<" and ">" are getting rendered as &lt; and &gt; in GenericItemResponse.ts

Description
"<" and ">" are getting rendered as < and > in GenericResponseItem

openapi-generator version
5.3.1

Command line used for generation
-g typescript-fetch
additionalProperties=typescriptThreePlus=true,prefixParameterInterfaces=true

Example of generated GenericItemResponse.ts :

export interface GenericItemResponse {
    /**
     * 
     * @type {Array<MyType1> | Array<MyType2>}
     * @memberof GenericItemResponse
     */
    items: Array<MyType1> | Array<MyType2> | null;
    /**
     * 
     * @type {number}
     * @memberof GenericItemResponse
     */
    size: number;
}

export function GenericItemResponseFromJSONTyped(json: any, ignoreDiscriminator: boolean): GenericItemResponse {
    if ((json === undefined) || (json === null)) {
        return json;
    }
    return {
        
        'items': Array&lt;MyType1&gt; | Array&lt;MyType2&gt;FromJSON(json['items']),
        'size': json['size'],
    };
}

Reproduce the issue with the reported typescript-fetch generator command and inspect the generated GenericItemResponse.ts output. Trace how the items type is rendered in the TypeScript fetch generator, then verify that angle brackets remain literal in both the JSDoc type and JSON conversion code.
