fix: fix use useSearchParams in useModel (#8545)

[zhangpanweb]

Close #8545

由于 BrowserRoutes 作为 children 传给 dataflow plugin，在 useModel 使用 useSearchParams，会导致无法获取 router context。修复方式为，将 BrowserRoutes 放置在外层，使 dataflow 相关 plugin 中都能够获取到 router context，从而顺利使用 router 相关 hooks

rootContainer 的含义是不是要保留，比如我，我目前为了让其在 router context 中，是这样做的，

参考 plugin-model 实现了一个 plugin-executor，他的 runtime 是

export function innerProvider(container, opts) {
  return React.cloneElement(
    container,
    null,
    <ProviderWrapper {...opts}>{container.props.children}</ProviderWrapper>,
  );
}
