Customize TOC style and template

Feature request

In my README I prefer to use the TOC-style where the links are listed below each other (like it is now) but in the CHANGELOG I prefer it inline next to each other divided with a middot (·).

Would be nice to have an option here to insert different styles of TOC in a file or have an option in settings.json to create our own templates. 😁

Style1:

- [Headline](#headline)
- [Subhead](#subhead)

Possible Style2:

[Headline](#headline) · [Subhead](#subhead)

How templating could work:

{
    "markdown.extension.toc.marker": "-",
    "markdown.extension.toc.template": "{marker} [{name}](#{link})",
    "markdown.extension.toc.template": "{list} [{name}](#{link})", // for ordered list

    "markdown.extension.toc.marker": "·",
    "markdown.extension.toc.markerSkipLast": true,
    "markdown.extension.toc.template": "[{name}](#{link}) {marker}",
}

The TOC is just an HTML list, and its style can be changed with CSS https://developer.mozilla.org/en-US/docs/Web/CSS/list-style

e.g. adding

<style>
    ul { list-style: none; }
</style>

in the Markdown file will remove bullets of all the unordered lists. To apply it only on the TOC, you may apply some CSS selectors depending on your document structure.

Yep sure @yzhang-gh. I will add an .editorconfig to prevent this in the future. Everyone has their own style and this would keep yours forced for your project.
