Clarify that some ParticleProcessMaterial properties have effect over the lifetime

[k0T0z]

Fixes #83603

[akien-mga]

Why remove the additional documentation about how it works with a CurveXYZTexture?

[k0T0z]

@akien-mga Hmmm, I forgot I am working on the scale, right, I will fix it

[ArtyIF]

I think it needs to apply to other properties like damping as well, but it needs to be double-checked first

[Mickeon]

This PR should probably be updated to include more properties other than scale_curve. If it can't, I mean... It is good by itself but it could be more meaningful.

[k0T0z]

Hmmmm, sure I mean why not, is there any other properties needed, I see we need the damping as well, is there anything else I am not aware of?

[Mickeon]

I looked at the whole list and it seems like the following properties seem to forget to mention the "over its lifetime" part.

• anim_offset_curve
• anim_speed_curve
• damping_curve
• hue_variation_curve
• linear_accel_curve
• orbit_velocity_curve
• radial_accel_curve
• tangential_accel_curve

color_initial_ramp may seem to be part of them at first, but it is initial, so I am not sure if it counts here.

[Mickeon]

The PR itself is completely fine. As I said before, I just wish it tackled more properties (which can be done later).

I had no "qualification" to approve it previously, but I can now.

[k0T0z]

I can add them some time anyway. Btw congrats for being able to approve now 🎉🎉🎉

Thanks!
