sdk/client: req marshal with []byte instead of *[]byte

[wuxu92]

The argument for request marshal is []byte not '*[]byte (the response is *[]byte)

so method below would failed with err: performing ReplaceContent: internal-error: payload must be *[]byte but got [xx xx]

go-azure-sdk/resource-manager/automation/2022-08-08/runbookdraft/method_replacecontent.go

Lines 24 to 40 in 32fa381

	func (c RunbookDraftClient) ReplaceContent(ctx context.Context, id RunbookId, input []byte) (result ReplaceContentOperationResponse, err error) {
	opts := client.RequestOptions{
	ContentType: "text/powershell",
	ExpectedStatusCodes: []int{
	http.StatusAccepted,
	http.StatusOK,
	},
	HttpMethod: http.MethodPut,
	Path: fmt.Sprintf("%s/draft/content", id.ID()),
	}
	req, err := c.Client.NewRequest(ctx, opts)
	if err != nil {
	return
	}
	if err = req.Marshal(input); err != nil {

Thanks for this @wuxu92, this looks ok to me, I would just make sure to update the error message for clarity.
