.vtu-files can not be parsed in Paraview v5.10.0-rc1

[patrickersing]

When trying to read in .vtu-files generated by Trixi2Vtk with Paraview v5.10.0-rc1 (the current version provided by the apt package manager) on Ubuntu 22.04.4 LTS, I get the following parsing error:

For me this could be fixed by installing a newer version Paraview 5.13 manually (it is not available in apt yet) or adding append=false to the vtk_grid() calls in vtktools.jl.

I had the same issues with the Paraview provided by Ubuntu 22.04 LTS. Using versions 5.7.0 and 5.12.0 work, though. Both provided directly by Paraview, bypassing apt.
