vscode-extensions.ms-vscode-remote.remote-ssh fails on vscode insiders

[sliedes]

Describe the bug

I have installed vscode-insiders on my NixOS machine using home manager (I do not believe this issue is HM-related; see below):

  programs.vscode = {
    enable = true;
    package = pkgs.vscode-insiders.overrideAttrs (oldAttrs: {
      nativeBuildInputs = oldAttrs.nativeBuildInputs ++ [
        pkgs.makeWrapper
      ];
      # The password store is not detected correctly on non-mainstream desktop environments
      postInstall =
        (oldAttrs.postInstall or "")
        + ''
          wrapProgram $out/bin/code-insiders --add-flags "--password-store=gnome-keystore"
        '';
    });
    mutableExtensionsDir = false;

    extensions =
      [
        pkgs.vscode-extensions.ms-vscode-remote.remote-ssh-edit
        pkgs.vscode-extensions.ms-vscode-remote.remote-ssh
      ]
      ++ (with pkgs.vscode-marketplace; [
          # ... stuff from nix-vscode-extensions flake
      ];
# ...

I am trying to connect from a NixOS machine to a NixOS remote. This fails to work, I believe because of a hard-coded path that is different on insiders:

Observe that the patch tries to find the node binary in ~/.vscode-server/bin/.../node, but the log says Found existing installation at ~/.vscode-server-insiders/.....

This might be a fix, but I need to sleep before testing it and sending a PR:
