Mistake in the linking docs

In the section Serializing and parsing params the example tries to achieve the following state

const state = {
  routes: [
    {
      name: 'Chat',
      params: { at: 1589842744264 },
    },
  ];
}

with the param named at.
But the path to it being chat/:date.

Meaning the resulting route param would be

params: {date: 1589842744264}

This needs fixing, and also I'm missing an option in renaming the state params from the path params.
As in this example we want to map chat/:date to at param.

从链接的“Serializing and parsing params”文档部分开始，并将 chat/:date 路径与所示的 at 状态参数进行比较。完成的标准是示例在内部保持一致，并且文档明确说明路径参数是否可以映射到名称不同的状态参数。
