chore(release): 4.7.0 [skip ci]

# [4.7.0](https://github.com/mob-sakai/ParticleEffectForUGUI/compare/v4.6.8...v4.7.0) (2024-06-19)

### Bug Fixes

* `UIParticle.transform.localScale` does not scale particles ([1d40e24](1d40e24c74)), closes [#313](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/313)
* UIParticle is scaled by canvas size even when `AutoScalingMode.None` and `ScalingMode.Local` ([54a4b1c](54a4b1cdfd)), closes [#313](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/313)
* UIParticle is scaled incorrectly with nested canvases ([f26920f](f26920f982)), closes [#313](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/313)

### Features

* reset previous position on start play for world space simulation ([3880484](3880484ce5)), closes [#303](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/303)
* restore `Transform.localScale` when setting `autoScalingMode` to something other than `Transform` ([5505247](5505247a94))
