astro/calcmysky: the port had been updated to version 0.3.1
This release fixes some rendering issues:
- On GPUs that compute mipmaps of non-power-of-two textures
poorly eclipsed atmosphere rendering now works as expected
- Atmosphere model examples now don't include Rayleigh phase
function in the texture -- this change fixes a "round cap
around zenith" artifact

astro/{calcmysky,stellarium}: update both ports to the latest versions
It's unfortunate transition time when they cannot be updated separately,
not at least without some ugly patching.
Make Stellarium use static release tarball instead of the generated by
GitHub one. While currently it does not win us much, next version will
be additionally offering smaller .tar.xz distfile which we'll switch to
more easily.
Enforce Qt5 build for now. While Stellarium and its dependencies are
Qt6-ready, providing correct and coherent flavors for all of them is
too much work for little gain. Everyone should be using Qt5 anyways.

astro/calcmysky: new port had been added (+)
CalcMySky is a software package that simulates scattering of light by
the atmosphere to render daytime and twilight skies (without stars).
Its primary purpose is to draw realistic sky in applications such as
planetaria, e.g. `astro/stellarium'.
