man worker: use kdoctools' kde-docs.css instead of kio_docfilter.css
kio_docfilter.css got out of sync with with kdoctools, e.g. for the header. Using the same CSS as the application manuals also results in visual consistency e.g. in khelpcenter.
One issue:
the footer
div has some styling with hardcoded height: 8.7em
(see https://invent.kde.org/frameworks/kdoctools/-/blob/master/common/en/kde-docs.css?ref_type=heads#L301). Which seems to have been added once to ensure consistence footer sizes on the webpages? (Added in unmaintained/kdelibs@5a78d45e)
Which is too much for the single info line added here:
Though actually also not perfect for small view widths with the application manuals, where the text overflows:
@mpyne @carlschwan Any ideas/proposals what to do here? Would it be fine to make the footer actually adapt to the content? Or have some variant for the web pages (e.g. https://docs.kde.org/stable5/en/gwenview/gwenview/index.html) vs. pages shown in khelpcenter? Or just some special rules for man pages?
