HarmonyOS 语言国际化时，切换不了马来语

参考以下demo：

@Entry
@Component
struct Index {
  @State message: Resource = $r("app.string.Hello_World");

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(30)
          .fontWeight(FontWeight.Bold)
        Image($r("app.media.p"))
          .width(100)
          .height(100)

        Button("设置偏好语言ms-MY").onClick((event: ClickEvent) => {
          T3("ms-MY")
          //如果设置的偏好语言找不到会默认用系统语言
        })
        Button("设置偏好语言zh-CN").onClick((event: ClickEvent) => {
          T3("zh-CN")
        })
        Button("设置偏好语言为fr-FR").onClick((event: ClickEvent) => {
          T3('fr-FR')
        })
      }
      .width('100%')
    }
    .height('100%')
  }
}

function T3(lType:string) {
  try {
    let appPreferredLanguage: string = I18n.System.getAppPreferredLanguage(); // 获取应用偏好语言
    console.info('preferredLanguage is:' + appPreferredLanguage)
  } catch (error) {
    let err: BusinessError = error as BusinessError;
    console.error(`call System.getAppPreferredLanguage failed, error code: ${err.code}, message: ${err.message}.`);
  }
  try {
    I18n.System.setAppPreferredLanguage(lType); // 设置应用偏好语言为zh-Hans 简体
    console.info(`setAppPreferredLanguage ${lType} succeed`)
  } catch (error) {
    let err: BusinessError = error as BusinessError;
    console.error(`call System.setAppPreferredLanguage failed, error code: ${err.code}, message: ${err.message}.`);
  }
}
