Revert "Keep release info up to date with other docbook files"
This reverts commit 9d99dbeb166cea454cd3667e5f6ffb71cbf84b4
A quick compare with the recent application did show that most
files are up to date, but some are not, which requires to revert
this commit according to the rules described at
https://cgit.kde.org/kdoctools.git/tree/src/template.docbook#n11
It would be nice to have this rules at a more public location.
