* gnu/packages/python-xyz.scm (python-jupyter-client-bootstrap): Make the base
package definition, moving most fields.  Update to 7.2.2.
[propagated-inputs]: Add python-entrypoints and python-nest-asyncio.
(python-jupyter-client): Inherit from python-jupyter-client-bootstrap,
adjusting accordingly.
[native-inputs]: Add python-pytest-asyncio.
