Generators/HTML: improve anchor links
As things were, the TOC would link to the section headers, but there was no straight-forward way to copy the link to a particular section once a user was viewing the section. This small change adds an invisible `§` character after each section title, which becomes visible when the user hovers over the title and allows for copying the permalink to that section. Includes updated test expectations.
