Add a setting for the header anchor symbol to remove (default is `#`)

[Lamecarlate]

Is your feature request related to a problem? Please describe.

I use markdownItAnchor to add id and link on my headings. By default, the link is on a # symbol. It can be changed in the settings, for example with §. But if it's not a # it's displayed in the table of contents.

I suppose that it's because of this line in SimplifyResults.js:

const text = $(el).text().replace(' #', '')

Describe the solution you'd like

I would like a setting in the toc plugin, in order to let it know what is the element to remove.

Additional context

With #

With §

FYI my fork https://github.com/uncenter/eleventy-plugin-toc has an option for this, ignoredElements - it is an array of selectors to remove from inside the headers. I'm not sure exactly what your HTML is here but I would guess you can set it to ['a'] to remove <a>/link elements.
