feat: EXE launcher no longer reject Java 11 and later.

* use api & implementation scope, instead of compile
* add shadow plugin back
  * related: https://github.com/huanghongxun/HMCL/pull/863
  * the duplicate entry bug is fixed
* move dependencies from root project to HMCLCore module

+
+我们发现，对于不经常检查邮箱的人来说，GitHub Issues 的反馈效率太低，时隔几个小时甚至一天的情况很多。为了改善反馈效率，并将积极为 HMCL 提供问题反馈和建议的人聚集起来，我们希望在这里反馈的人可以在 HMCL 3 用户 QQ 群：219177735 中反馈信息，**而不在 GitHub Issues 中反馈问题**。
+
+如果你希望在 QQ 群中反馈问题，也请将下面的信息表填好直接发在群中，加快我们的沟通速度。
+
+
+
+# 问题提交
+
+*完整地填下面的问题提交表对我们很重要，这可以加快我们分析问题原因的速度。*
+
+* 启动器版本：
+* 操作系统：
+* Java 版本：
+* 错误截图（最好请将整个电脑屏幕的截图发上来）：
+* 游戏版本（如果是启动通过启动器自带的自动安装功能安装的游戏）：
+* 对游戏做的修改（是否自行通过安装器安装 Rift 等 API，以及 mod）：
+* 游戏崩溃报告（如果有）：
+* 启动器崩溃报告（如果有）：
+* 启动器日志文件（出现问题后点击启动器设置中的【导出启动器日志】按钮）：
+* 问题描述（如何触发问题）：
