gnu: python-ginga: Swap inheritance.

Ginga project positions as a final application and Python library, this
change swaps inheritance with ginga.

* gnu/packages/astronomy.scm (ginga): New variable, moved from
python-ginga, sort alphabetically.
[native-inputs]: Add python-setuptools-next.
[inputs]: Moved from propagated-inputs; remove python-pyqt and add
python-pyqt-6.

(ginga-qt5): Deprecate variable.

(python-ginga): Inherit from ginga.
[propagated-inputs]: Keep only "install-requirements".
Remove opencv, python-astroquery, python-dateutil, python-exif-read,
python-fitsio, python-magic, python-matplotlib, python-photutils,
python-scipy, and python-tomli.
