[Website] Specification identifier missing in actual HTML title #2267

There is a rather annoying issue with the current specification.

While the H1 header on the current LSP specification is Language Server Protocol Specification - 3.17, the HTML attribute title is just Specification. I think that this is a usability issue: If you mail the page URL or link the webpage to a desktop folder, you have to manually change the title (email subject, link name), also browser plugins that help collect (and format) URL and title are less useful. I wasn't able to fully figure out how the HTML generation works from the Markdown-embedded metadata like in specification.md, but I'd expect that title is used within in <title></title> while fullTitle would be a better option.

P.S. Another issue is that the navigation between versions collides with the actual content (v3.17 vs. v3.18 - which one is current?).
