[WIKI] Generate Sections TOC for anchor navigation in a Wiki page
Description
When writting big Markdown Wiki page you can split it in sections for readability. But it lacks a TOC to quick navigate to a section.
Benefit will be to encourage use of sections because it will automatically show in a Sections TOC on each Wiki page.
Proposal
Parse the Markdown to catch section headings for the first N levels and add a TOC at the top of the Wiki page with anchor hyperlinks showing sections headings.
Links / references
Dokuwiki does it well.
It is somewhat linked to #18409 (moved) because it gives more usability to sections
