Subject: gnu: python-pyqtgraph: Reduce closure size, don't propagate Qt5/Qt6.

Don't propagate Qt5/Qt6 and let the user of the package to select which
one is required.

From project's documentation:

  When pyqtgraph is first imported, if the environment variable
  PYQTGRAPH_QT_LIB is not set, it automatically determines which library
  to use by making the following checks:

    - If PyQt6 is already imported, use that
    - Else, if PySide6 is already imported, use that
    - Else, if PyQt5 is already imported, use that
    - Else, if PySide2 is already imported, use that
    - Else, attempt to import PyQt6, PySide6, PyQt5, PySide2, in that
    order.

See: <https://pyqtgraph.readthedocs.io/en/pyqtgraph-0.13.7/getting_started/how_to_use.html#pyqt-and-pyside>.

* gnu/packages/python-science.scm (python-pyqtgraph)[arguments]
<test-flags>: Run unit tests only, skip one more failing test, run in a
single thread.
[inputs]: Remove qtbase-5.
[propagated-inputs]: Remove python-pyqt.
[native-inputs]: Remove python-pytest-cov, python-pytest-xdist, and
python-wheel; add python-pyqt-6 and python-pytest-qt.
