The debian package postinst script should not (unconditionally) install/configure the apt repository. That goes against the expectation that we, the administrators, are in control of all the repository sources. Also, having a .deb setup the repository source, is a really weird pattern, as one will have a new package source that we have no idea what created it (e.g. dpkg -S does not return that file).

So please, drop that part of the code, and do not install /etc/apt/sources.list.d/vscode.list.
