Pyvista not available with docker due to lack of vtk

Did you make sure to pull the latest image (docker pull dolfinx/lab)?
Calling the command:

and then

 python3 -c "import dolfinx; print(dolfinx.common.git_commit_hash); import pyvista; print(pyvista.__version__)"

returns

1b27281ac329f1cd1fd7cb3e2d66096e53ad47c3
0.34.2

for me.
