Fix the style-lint errors and warnings for wiki.scss

Closes #59829

See merge request gitlab-org/gitlab-ce!31656

There were two errors: duplicate styles and @extend used with a class
name. I added `.top-area` class to all the instances where
`.wiki-page-header` is used since %top-area didn't really make a lot of
sense as a placeholder selector. This is also consistent with behaviour
on other pages where the `.top-area` class is used alongside the other
classes for the specific header styling.
