Resolve "Optimize visual representation of skeleton coming vfrom c3d"

Update .gitlab-ci.yml file

The building of the installer in the CI is broken, because dependencies are not properly set. The Windows-CI fetched th artifacts from Mac

`C:\GitLabRunner\builds\R5KJi7Pq\0\ped-dyn-emp\petrack\build\_CPack_Packages\Darwin\DragNDrop`

which results in the failure of some scripts. I made Windows not depend on anything, since it builds PeTrack again and made the MacOS job depend on `build_macos` so it fetches the already built bundle.

I'll comment out the part which only allows these to run on master, so we can test it. 

- [ ] include only on master constraint again
