HarmonyOS RNOH使用@react-navigation/bottom-tabs问题

本库依赖以下三方库，请查看对应文档：

@react-navigation/native:https://gitee.com/react-native-oh-library/usage-docs/blob/master/zh-cn/react-navigation-native.md

@react-native-oh-tpl/elements:https://gitee.com/react-native-oh-library/usage-docs/blob/master/zh-cn/react-navigation-elements.md

@react-native-oh-library/react-native-safe-area-context:https://gitee.com/react-native-oh-library/usage-docs/blob/master/zh-cn/react-native-safe-area-context.md

本库HarmonyOS侧实现依赖@react-native-oh-library/react-native-safe-area-context的原生端代码，如已在HarmonyOS工程中引入过该库，则无需再次引入，可跳过本章节步骤，直接使用。

如未引入请参照@react-native-oh-library/react-native-safe-area-context:https://gitee.com/react-native-oh-library/usage-docs/blob/master/zh-cn/react-native-safe-area-context.md#link文档的Link章节进行引入。
