[BUG] GET methos query option bug

[rhkdgns95]

Bug Report Quick Checklist

• I am on the latest version of swagger-typescript-api (v8.0.3)
• I use package manager yarn.
• I run swagger-typescript-api on OS Window 10 PRO.
• I run swagger-typescript-api on Node.js v12.16.1

Describe the bug

(async () => {
  const res = await api.pet.findPetsByStatus({
    status: ["pending", "available"],
  });
  console.log("RES: ", res);
})();

• It becomes a code generator normally.
• However, if you write an array string in the query content when requesting the GET method, the character value is requested along with the index value, not the string corresponding to the first index of the string array.

ex) https://petstore.swagger.io/v2/pet/findByStatus?status=available&status=pending&status=sold

Current situation

0=p&1=v     // pending [0] : "p" + available [1] : "v"

Expected

status=pending&status=solid&status=available

To Reproduce

• _generated_/index.ts

  private addArrayQueryParam(query: QueryParamsType, key: string) {
    const value = query[key];
    if (Array.isArray(value) && ["string", "number", "boolean"].includes(typeof value[0])) {
      return value.map((v) => `${key}=${v}`).join("&");
    } else {
      return `${value.map(this.addQueryParam).join("&")}`;
    }
  }
