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

首先閱讀 src/Plotly.NET.ImageExport/PuppeteerSharpRenderer.fs，並將其渲染流程與連結的 jsdom 方法以及 edge 的 Node.js 執行模型進行比較。定義以 Node.js 為基礎的渲染器整合方式，並驗證 Plotly.NET JSON 物件可以在不使用無頭瀏覽器的情況下進行渲染並儲存為影像。
