[bug#68556] [PATCH gnome-team v7 2/7] gnu: gnome-shell-extensions: Wrap the extensions.

[Vivien Kraus]

The top-level modules that are wrapped are the /extension.js and /prefs.js of
every extension sub-directory. The GI_TYPELIB_PATH used contains glib for
every extension, and gnome-menus for Applications Menu.

* gnu/packages/gnome.scm (gnome-shell-extensions) [#:phases]: Add
'wrap-extensions.
[native-inputs]: Add gobject-introspection.
[inputs]: Add gnome-menus and glib.
[propagated-imputs]: Remove glib.
