SDL2 wiki navbar link button element "front page" false redirect to SDL3/frontpage

[shencan03]

Scenario: Click "front page" button at https://wiki.libsdl.org/SDL2/SDL_CreateWindow from navbar -> redirected to https://wiki.libsdl.org/SDL3/FrontPage

Technically, that "Front Page" link at the top means the whole wiki's homepage, not a subsection.

But we are changing the text on the left of that navbar to "SDL2 wiki" and it's a link to SDL2's front page. I'm inclined to say we should change this to:

• always say "SDL wiki" on that left-side text
• always have that link go to https://wiki.libsdl.org/ (the whole wiki's front page).
• change the "Front Page" link to go to the subsection's front page.

Going to think about this a bit before I do anything, though. I'm not sure what I think is best here, yet.
