Subject: gnu: python-sparqlkernel: Use gexps and fix inputs.

[arguments]: Use gexps.
[tests?]: Add comment.
[phases]: Delete trailing #t.
{no-custom-css}: Use a regular lambda.
{install-kernelspec}: Move after the add-installed-pythonpath phase.  Remove
now extraneous add-installed-pythonpath call.  Adjust for gexps.
[native-inputs]: Delete field.
[propagated-inputs]: Add python-ipykernel, python-notebook, python-rdflib and
pythopython-traitlets.
[description]: Avoid '&' in description.
