🐞 Description of the bug

When installing the latest dev version from main without the [all] extra, importing ansys.meshing.prime raises the following exception:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "D:\ANSYSDev\public\pyprimemesh\.venv2\lib\site-packages\ansys\meshing\prime\__init__.py", line 5, in <module>
    from ansys.meshing.prime.core.model import Model
  File "D:\ANSYSDev\public\pyprimemesh\.venv2\lib\site-packages\ansys\meshing\prime\core\model.py", line 41, in <module>
    from ansys.meshing.prime.core.mesh import Mesh
  File "D:\ANSYSDev\public\pyprimemesh\.venv2\lib\site-packages\ansys\meshing\prime\core\mesh.py", line 29, in <module>
    import pyvista as pv
ModuleNotFoundError: No module named 'pyvista'

After manually installing PyVista:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "D:\ANSYSDev\public\pyprimemesh\.venv2\lib\site-packages\ansys\meshing\prime\__init__.py", line 5, in <module>
    from ansys.meshing.prime.core.model import Model
  File "D:\ANSYSDev\public\pyprimemesh\.venv2\lib\site-packages\ansys\meshing\prime\core\model.py", line 41, in <module>
    from ansys.meshing.prime.core.mesh import Mesh
  File "D:\ANSYSDev\public\pyprimemesh\.venv2\lib\site-packages\ansys\meshing\prime\core\mesh.py", line 30, in <module>
    from ansys.tools.visualization_interface import MeshObjectPlot
ModuleNotFoundError: No module named 'ansys.tools'

I think the root cause is that the visualization code is imported as part of the default import, but ansys-tools-visualization-interface is present only installed when the [all] extra is used on install.

📝 Steps to reproduce
