Bug#1042478: Tasks missing in tasksel and its task-description file

[d3vf4n]

Package: tasksel
Version: 3.73

There are tasksel tasks that
 1. The command "tasksel --list-tasks" does not list.
 2. They do not show either in the task description file 
"/usr/share/tasksel/descs/debian-tasks.desc"

Some examples are the tasks "science-tasks", "electronic-tasks", 
"education-tasks", and quite a few more:
https://packages.debian.org/search?suite=bookworm&section=all&arch=any&searchon=all&keywords=tasksel
https://packages.debian.org/search?suite=bookworm&section=all&arch=any&searchon=names&keywords=live-task-

Despite all this, tasksel can actually install them: for instance, "tasksel -t 
install science-tasks".

I am on: Debian 12.1 (bookworm),
kernel version (output of "uname -v"): #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-1
