[Maxim Cournoyer <maxim.cournoyer@gmail.com>]

* gnu/packages/inkscape.scm (inkscape/stable)
[phases]: Wrap with PATH and GI_TYPELIB_PATH.
[inputs]: Sort inputs.  Add python-appdirs, python-cssselect, python-pygobject
and python-requests.
(inkscape) [inputs]: Do not append python-cssselect.

Fixes: https://issues.guix.gnu.org/63938
