chore(release): 5.0.0-preview.1 [skip ci]

# [5.0.0-preview.1](https://github.com/mob-sakai/ParticleEffectForUGUI/compare/v4.6.6...v5.0.0-preview.1) (2024-05-23) ### Features * add project settings for UIParticle ([b6e6185](b6e6185c52)) * change the default value of `UIParticle.scale` from `10` to `1` ([1b3c0f9](1b3c0f92dc)), closes [#310](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/310) * UIParticle no longer inherits from MaskableGraphic ([b6d921b](b6d921b3e4)) ### BREAKING CHANGES * Some members inherited from MaskableGraphic will no longer be available.

-  - **Transform:** Transform.lossyScale (=world scale) will be set to (1, 1, 1).
-  - **UIParticle:** UIParticle.scale will be adjusted.
- **Use Custom View:** Use this if the particles are not displayed correctly due to min/max particle size.
