[优化] 使用 Gradle Platform 统一管理项目依赖

[ReaJason]

https://docs.gradle.org/current/userguide/platforms.html

Platforms are used to ensure that all dependencies in a project align with a consistent set of versions.

Platforms help you manage and enforce version consistency across different modules or libraries, especially > when you are working with a set of related dependencies that need to be kept in sync.

随着子模块越来越多，每个模块可能会使用到相同的依赖，因此为了简化依赖的编写（写版本号实在是太麻烦了），因此需要像 SpringBoot 一样的 dependency-manager 的东西来管理依赖，引入依赖将不再需要编写版本号，而 Gradle Platform 刚好能满足这种需求。
