Result._plot_point_scalars: correct pyvista version check for version…

… 0.32.dev0

The actual development version is 0.32.dev0: `pv._version.version_info = (0, 32, "dev0")`. There, the string `"dev0"` can not be compared with `0`, so that comparison failed for this version. To solve this, I removed the last element on the right-hand side expression of the comparison. The new comparison `(0, 32, "dev0") > (0, 32)` works now as expected. Tested manually.
