docs: add permanent link chain icon to headings without impacting SEO (#1746)

I noted that there are no permanent links in the docs. Adapted the
current best solution from
https://github.com/squidfunk/mkdocs-material/discussions/3535. It adds a
GitHub-like chain icon to the left of each heading (right on mobile) and
does not impact SEO unlike the default solution with pilcrow char `¶`
that might show up on google search results.
