This fixes the broken "Linux (AppImage)" CI job.
Some systems (e.g. Ubuntu 22.04, which we use to make the AppImage), have ancient versions of meson and ninja, which is not good when we have dependencies like PyGObject 3.47+ (and more recently, one of its transitive dependencies, pycairo 1.27+) requiring a fairly recent version of meson to be able to be built.
So, instead of relying on whatever meson/ninja version the current system provides us with to make the AppImage, this change will simply install up-to-date, official wheels of meson/ninja directly from PyPI.
This also allows us to finally unpin PyGObject's version.
