ci(quality): revert aggressive doc/man/locale cleanup that broke ROS apt install

The aggressive disk cleanup in the prior commit rm'd /usr/share/doc,
/usr/share/man and /usr/share/locale. dpkg postinstall scripts for
ros-jazzy-desktop, openjdk-21, libvtk9 and libpcl-dev fail when those
trees are missing - the ASan job aborted after 5 min in 'Set up ROS 2
Jazzy' with dpkg returning 100 on every dependency.

Roll those three rm -rf paths back. Keep the RelWithDebInfo build-type
change (which was the actual fix for the ASan disk-space failure) and
the df -h diagnostic.
