gnome-session: remove outdated workaround and fix overwriting lang
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **YES**

If you want me to re-add the autostart-app patch, feel free to let me know.
I used GDM_LANG since it is stated here for this purpose (resetting lang after loading `/etc/profile`), but it seems to come from the GDM 2 days and I don't see any current docs referencing it, so I'm not sure I should be using it: https://gitlab.gnome.org/GNOME/gdm/-/blob/42.0/docs/ko/ko.po#L837-839

Closes: https://github.com/void-linux/void-packages/issues/15292
