This mainly addresses `double-space after sentence end period' and `trailing
white space' issues.

* gnu/packages/astronomy.scm (python-tweakwcs): Fix description.
* gnu/packages/check.scm (python-pytest-subtesthack): Fix description.
* gnu/packages/python-xyz.scm (python-qnorm, python-uncertainties,
python-sre-yield): Fix description.
* gnu/packages/qt.scm (python-pyqt6-sip): Fix description.
