Allow edit URL to be customized with doc metadata

[Glavin001]

Motivation

Some of the Markdown docs are generated and therefore should not be edited. Instead contributors should edit the source data files (e.g. .json or .yaml or otherwise) which are used to generate the final Markdown docs.

Test Plan

Documentation has been updated to reflect usage.

Example:

---
id: options
title: Options
sidebar_label: Options
edit_url: https://github.com/unibeautify/unibeautify/edit/master/src/options.ts
---

Notice the Edit Button in the following screenshot does not have a link in the conventional editUrl format. In this screenshot my cursor is hovering over the Edit Button and its URL is shown in the bottom left corner.

Hi @Glavin001. Thank you very much for this pull request. And the great detail you provided for it, especially the test plan and the live demo.

I think I am going to merge this. I might have a question or two as I review it. But looks good on the surface.

[JoelMarcey]

This is great I think 👍

Only one thing is concerning me. It is something small, but could be important if we decide we want to change it in the future -- easier to change now.

Do you think the name edit_url is the best name? It indeed may be - but what I am thinking is that it is so close to editUrl that it has the possibility of becoming confusing.

Would doc_specific_edit_url be better? Or is that too long, in your opinion?

[Glavin001]

I agree. Maybe omit the specific part and go with doc_edit_url or custom_edit_url? 🤔

[JoelMarcey]

@Glavin001 custom_edit_url seems good to me. Want to make that change? And then I can merge this in. Thanks!
