Request to support Class-Path attribute in plugin Jar

Your current Halo version

2.5.0-SNAPSHOT

Describe this feature

Currently, when building plugin, all dependencies are flatten into root of plugin Jar. It might override the META-INF folder.

It would be better if we move all dependencies into libs folder in plugin Jar and refine Class-Path attribute into MANIFIST.MF. See https://docs.oracle.com/en/java/javase/17/docs/specs/jar/jar.html#class-path-attribute for more. So that we cloud load dependencies automatically.
