Bug#1049426: debian installer on, testing iso (trixie) generates stable source.list (bookworm)

[Laurent Stella <olaulau@gmail.com>]

Package: debian-installer-launcher

Version: unknown

When trying to install debian testing from a testing iso, the installed 
system has bookwork in his /etc/apt/source.list.

Same behavior with all those methods :
- using netinst iso
- using live iso (running installer from the grub)
- using live iso (running installer from the live session)

The live session has correct source.list (Trixie) but the resulting OS 
has Bookworm sources, despite having recent packages such as 6.4 kernel.
Done this several times on real and virtual machine, with today 
downloaded testing iso from debian website.

By the way, new installer (form the live session) is great !
Any hope it could replace  the old netinst installer ? maybe by 
integrating optional steps to satisfy technical cases.
