Port to mozjs140 #129
Description
mozjs140 was released in June and is now available in several distros including Debian Testing (forky), Ubuntu 24.10, and Fedora 43.
gjs 1.85.2 (part of GNOME 49 Beta) includes support for mozjs140.
The new gjs switched from libgirepository-1.0-1 to libgirepository-2.0-0 which is something you may want to do also. libgirepository-2.0-0 is available in Debian 13 and Ubuntu 24.04 LTS but not in older distros. Confusingly, the gir is gir1.2-girepository-3.0 for the 2.0 API (gir1.2-girepository-2.0 was for the 1.0 API).
