Fix CI issues with oxygen links
This simply removes the following CI errors:
products/frameworks/index.html
Non-OK status: 404 --- products/frameworks/index.html --> https://api.kde.org/frameworks/oxygen-icons5/html/index.html
frameworks/oxygen-icons/index.html
Non-OK status: 404 --- frameworks/oxygen-icons/index.html --> https://api.kde.org/frameworks/oxygen-icons5/html/index.html
This will be insta-merged for now, later we can check if we can actually delete the frameworks/* pages and fix the products/frameworks/* pages altogether.
For posterity: it seems the root cause for the links to stop working was frameworks/oxygen-icons!9 (merged), which stops Oxygen Icons docs from being built for Qt5.
