gnu: python-jupyter-core: Improve package.

* gnu/packages/python-xyz.scm (python-jupyter-core): Use
  G-expressions. Fix indentation.
  [arguments] <test-flags>: Skip test requiring python-pip; refactor
  with STRING-JOIN.
  [native-inputs]: Remove python-pip, python-pre-commit, and
  python-pytest-cov.
