gnu: python-glue-astronomy: Reduce closure size.

Keeping python-pyqt in scope introduces profile collusion, see
<https://codeberg.org/guix/guix/issues/6371#issuecomment-10558598>,
this change removes optional inputs.

    gnu/packages/astronomy.scm:5270:2: python-glue-astronomy@0.14.0:
    propagated inputs python-pyqt@6.9.1 and python-pyqt@5.15.11 collide

* gnu/packages/astronomy.scm (python-glue-astronomy):
[propagated-inputs]: Remove python-pyqt and python-reproject.
