chore: update publishing

[PierreSchwang]

Description

Follows PlotSquared and updates the Sonatype publishing.
The plugin is quite limited when facing custom setups - it requires the java or java-library plugin to work. That's not really working for the libs - but as the platform setup is basically just specifying a publication, cloning that behavior is not really hard. Only annoying thing is the log messages:

> Configure project :worldedit-libs:core
No compatible plugin found in project :worldedit-libs:core for publishing

> Configure project :worldedit-libs:bukkit
No compatible plugin found in project :worldedit-libs:bukkit for publishing

> Configure project :worldedit-libs:cli
No compatible plugin found in project :worldedit-libs:cli for publishing

> Configure project :worldedit-libs:core:ap
No compatible plugin found in project :worldedit-libs:core:ap for publishing

I couldn't really test much here. The tasks are running and I'm receiving my Unauthorized response. The generated POMs and module-JSONs are looking correct.

FAILURE: Build completed with 3 failures.

1: Task failed with an exception.
-----------
* What went wrong:
A problem was found with the configuration of task ':worldedit-cli:plainJavadocJar' (type 'JavadocJar').
  - Gradle detected a problem with the following location: '/home/runner/work/FastAsyncWorldEdit/FastAsyncWorldEdit/worldedit-cli/build/libs/worldedit-cli-2.13.1-SNAPSHOT-javadoc.jar'.
    
    Reason: Task ':worldedit-cli:generateMetadataFileForMavenPublication' uses this output of task ':worldedit-cli:plainJavadocJar' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
    
    Possible solutions:
      1. Declare task ':worldedit-cli:plainJavadocJar' as an input of ':worldedit-cli:generateMetadataFileForMavenPublication'.
      2. Declare an explicit dependency on ':worldedit-cli:plainJavadocJar' from ':worldedit-cli:generateMetadataFileForMavenPublication' using Task#dependsOn.
      3. Declare an explicit dependency on ':worldedit-cli:plainJavadocJar' from ':worldedit-cli:generateMetadataFileForMavenPublication' using Task#mustRunAfter.
    
    For more information, please refer to https://docs.gradle.org/8.14.3/userguide/validation_problems.html#implicit_dependency in the Gradle documentation.

* Try:
> Declare task ':worldedit-cli:plainJavadocJar' as an input of ':worldedit-cli:generateMetadataFileForMavenPublication'
> Declare an explicit dependency on ':worldedit-cli:plainJavadocJar' from ':worldedit-cli:generateMetadataFileForMavenPublication' using Task#dependsOn
> Declare an explicit dependency on ':worldedit-cli:plainJavadocJar' from ':worldedit-cli:generateMetadataFileForMavenPublication' using Task#mustRunAfter
