Fix deprecation message for rotation volume

[shreyas-flex]

• Updates message for new Sphere entity in RotationVolume

---

Note

Low Risk
String/message update and a non-functional formatting tweak; no changes to meshing translation logic.

Overview
Updates the RotationCylinder deprecation message to correctly state that RotationVolume supports Sphere entities in addition to Cylinder and AxisymmetricBody.

Applies a small formatting-only change to the cylindrical_refinement_translator function signature (no behavior change).
