Cleanup additional Linux dependencies on conda and fix CI

More and less ~1 week ago the conda CI job started failing with error:

I am not sure what changed, but anyhow switching to xorg-xorgproto and libgl-devel is the right thing to do, see conda-forge/conda-forge-pinning-feedstock#6688 and conda-forge/conda-forge-pinning-feedstock#6816 .

Note that the proper solution is to add a glfw3-devel package that depends on all the required packages (see RoboStack/robostack.github.io#65) but as a fast solution manually adding the transitive *-devel dependency is perfectly fine.
