Add ImageExport renderer based on running node.js

Description

As plotly.js, the underlying library that Plotly.NET is using needs an environment that can execute javascript to render images programmatically.

https://github.com/tjanczuk/edge seems to be able to run javascript code in node.js from .NET, meaning it should be possible to use plotly.js to render our json objects and save them to a file via node. This would be a big addition, because it would not need a headless browser to achieve this, just a node installation.

Pointers

• here is an answer that shows how to do this with jsdom: https://stackoverflow.com/a/76070903/5675597
• A reference implementation for this using PuppeteerSharp can be seen here

首先阅读 src/Plotly.NET.ImageExport/PuppeteerSharpRenderer.fs，并将其渲染流程与链接的 jsdom 方法以及 edge 的 Node.js 执行模型进行比较。定义基于 Node.js 的渲染器集成方式，并验证 Plotly.NET JSON 对象可以在不使用无头浏览器的情况下进行渲染并保存为图像。
