This commits adds a new emitter type for particles material
and 3D CPU particles. The new emitter is called "ring"
and it can emit either in a ring or cylinder fashion.
This adds the following properties for the emitter:
1. ring_emitter_axis: the axis along which the ring/cylinder
will be constructed
2. ring_emitter_radius: outer radius of the ring/cylinder
3. ring_emitter_inner_radius: inner radius of the cylinder.
when set to zero, particles will emit in the full volume.
4. ring_emitter_height: height of the ring/cylinder emitter.

We already removed it from the online docs with #35132.
Currently it can only be "Built-In Types" (Variant types) or "Core"
(everything else), which is of limited use.
We might also want to consider dropping it from `ClassDB` altogether
in Godot 4.0.
- Add some missing descriptions.
- Add links to tutorials for ARVR and AnimationTree.
- Style fixes.
- Engine changes:
* Make `AnimationNodeTransition.input_<number>` properties internal
so that they don't appear in the docs. They still appear in the
inspector based on the actual number of inputs requested.
* Drop unimplemented `CPUParticles.flatness`. It's only used for 3D
particles in `ParticlesMaterial`, and thus only relevant for
`CPUParticles3D`.
Setters and getters have been hidden from the documentation when the matching
properties have been exposed, but some of them are parametric and require the
name or index of a given parameter to be used. So they need to be properly
documented with the type and name of the arguments they take.
For example, CPUParticles' `set_param(Parameter param, float value)`.
- Document a few more properties and methods
- Add more information to many classes
- Fix lots of typos and gramar mistakes
- Use [code] tags for parameters consistently
- Use [b] and [i] tags consistently
- Put "Warning:" and "Note:" on their own line to be more visible,
and make them always bold
- Tweak formatting in code examples to be more readable
- Use double quotes consistently
- Add more links to third-party technologies
It took me some hours of trying and wondering and one question with a very helpful answer in the facebook group to figure out that the color_ramp gradient actually modifies the vertex color of the particle mesh (but NOT the albedo). After knowing this enabling vertex_color_use_as_albedo in the SpatialMaterial led to success.
I hope adding this little hint:
"Each particle's vertex color will vary along this [GradientTexture]."
Might help other people which stumble upon this...
