Fix conduit rectilinear grid dimensions
Closes: #18580 (closed)
Fix issues with rectilinear grid conduit mesh that are converted to VTK objects through vtkConduitSource
object:
- allow 2D rectilinear grid, the
values/z
is not mandatory - allow different x/y/z dimension - this was likely a typo error where
xArray
was used for y and z coordinates
