feat(seo): shift h1 tag from logo to discussion title (#3724)

* feat(seo): shift h1 tag from logo to discussion title

Many times have we seen opponents of using h2 as the discussion title. Although
my own SEO knowledge is limited, I have seen the importance of structuring pages
according to the content you wish to prioritize. If we only take that into consideration
there is zero reason for the app-wide identical logo to take precedence over any
other heading.

This change makes the logo a standard (visually identical) element, and
makes the discussion hero title a h1.

* feat(seo): rewrite remainder of hero titles and subtitles
