### Godot version

v4.1.1.stable.official [bd6af8e0e]

### System information

Godot v4.1.1.stable - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3050 Ti Laptop GPU (NVIDIA; 31.0.15.3640) - 12th Gen Intel(R) Core(TM) i7-1260P (16 Threads)

### Issue description

The `CylinderMesh` has an option for rings within the geometry. You cannot set this to zero. This results in artefacts when rendering a `CylinderMesh` using transparency without backface culling, made worse in combination with emission.

Transparent material without backface culling. One ring:

The desired effect can be somewhat achieved by tweaking the shading mode, but I would suggest allowing to set the number of rings to zero. The desired outcome would be a single cylinder without any rings in the middle.

### Steps to reproduce

1. Create a new `CylinderMesh`
2. Try to select zero rings
3. Minimum of one ring is enforced by the editor
