HarmonyOS picker选择器的数据源问题

当前textPicker不支持label/value形式：

可以获取选择器值的索引，根据索引自行封装映射

下面一个demo可以参考：

interface Fruits {
  id: number
  name: string
}

@Entry
@Component
struct TextPickerExample {
  private select: number = 1
  private fruitsList: Fruits[] = [
    { id: 1, name: "apple1" },
    { id: 2, name: "orange2" },
    { id: 3, name: "peach3" },
    { id: 4, name: "grape4" },
  ]

  build() {
    Column() {
      TextPicker({ range: this.fruitsList.map((item) => item.name), selected: this.select })
        .onChange((value: string | string[], index: number | number[]) => {
          console.info('Picker item changed, value: ' + value + ', index: ' + index)
          this.fruitsList[index.toString()].id;
        })
        .disappearTextStyle({ color: Color.Red, font: { size: 15, weight: FontWeight.Lighter } })
        .textStyle({ color: Color.Black, font: { size: 20, weight: FontWeight.Normal } })
        .selectedTextStyle({ color: Color.Blue, font: { size: 30, weight: FontWeight.Bolder } })
    }.width('100%').height('100%')
  }
}
