vscode.list is always added on Debian

• VSCode Version: 1.49.3-1601661857
• OS Version: Debian bullseye/sid

I found multiple similar issues but all were closed, so opening a new one. The problem is that code.postinst unconditionally adds /etc/apt/sources.list.d/vscode.list unless it is not there. I renamed this file to establish a stable order of repos (to resolve cases where multiple repos have the same package), and then also switched to the new ".sources" format. This results in duplicate entries for vscode whenever a new version of vscode is released (and thus code.postinst is executed).

One (hopefully easy) way out would be to add a flag which controls whether code.postinst runs this code or not.

Does this issue occur when all extensions are disabled?: Yes
