gnu: Move search path JUPYTER_PATH.

python-jupyter-core provides the `jupyter` binary as well as generic
functions to discover the search path for all Jupyter subprojects. Thus
it should provide the search paths too.

* gnu/packages/python-xyz.scm (jupyter): From here…
(python-jupyter-core): …to here.
[native-search-paths]: Add JUPYTER_CONFIG_DIR, because some Jupyter
projects install config files to their etc/ directory and expect them to
be loaded automatically.
