chore(release): 5.0.0-preview.4 [skip ci]

# [5.0.0-preview.4](https://github.com/mob-sakai/ParticleEffectForUGUI/compare/v5.0.0-preview.3...v5.0.0-preview.4) (2024-06-27)

### Bug Fixes

* generated baking-camera object remains in the prefab or scene (again) ([5babd6d](5babd6d07b))
* SetParticleSystemInstance/Prefab APIs destroy generated objects ([4b30c16](4b30c16b9a))

### Features

* add 'custom view' option. ([4252f11](4252f1199b))
* restore `Transform.localScale` when setting `autoScalingMode` to something other than `Transform` (again) ([04232b6](04232b6749))
* the rendering order list in inspector is now more compact ([9212eaa](9212eaa84c))

+- **Particle System**: Attracts particles generated by the specified particle system.
 - **Destination Radius**: Once the particle is within the radius, the particle lifetime will become 0, and `OnAttracted`
   will be called.
 - **Delay Rate**: Delay to start attracting. It is a percentage of the particle's start lifetime.
