Fix pebble for array-type query parameter

[habara-k]

Description

This PR addresses a modification to the generator responsible for producing the Go SDK from OpenAPI definitions. Specifically, it introduces support for query parameters that include arrays.

Changes

Enhanced the generator to handle array-type query parameters.

Here is an example of how such an API call might look in a shell script:

curl -X GET "https://api.line.me/v2/bot/example?param=value1&param=value2"

Note

Currently, there are no endpoints that utilize such parameters. However, this update is a preparatory step for future API enhancements.

Code before the change

func (client *MessagingApiAPI) GetResourceWithHttpInfo(
	param *[]string,
) (*http.Response, *MessagingApiGetResourceResponse, error) {
	path := "/v2/bot/example"

	req, err := http.NewRequest(http.MethodGet, client.Url(path), nil)
	if err != nil {
		return nil, nil, err
	}

	query := url.Values{}
	query.Add("params", string(params)) // Error! cannot convert status (variable of type *[]string) to type string

	// ...

Code after the change

func (client *MessagingApiAPI) GetResourceWithHttpInfo(
	param *[]string,
) (*http.Response, *MessagingApiGetResourceResponse, error) {
	path := "/v2/bot/example"

	req, err := http.NewRequest(http.MethodGet, client.Url(path), nil)
	if err != nil {
		return nil, nil, err
	}

	query := url.Values{}
	for _, v := range *params {
		query.Add("params", v)
	}

	// ...
