Fix classifier Property Issue in Gradle Build

[neotheprogramist]

Description

This PR addresses a build failure in the besu-verkle-trie project while executing the gradle command. The error was caused by the use of the deprecated classifier property in the build.gradle file.

Error Details

Running the gradle command resulted in the following error:

$ gradle

FAILURE: Build failed with an exception.

* Where:
Build file './besu-verkle-trie/build.gradle' line: 111

* What went wrong:
A problem occurred evaluating root project 'besu-verkle-trie'.
> Could not set unknown property 'classifier' for task ':sourcesJar' of type org.gradle.api.tasks.bundling.Jar.
...

Cause

The issue was due to the use of the classifier key, which has been deprecated. The problematic code snippet was:

  task sourcesJar(type: Jar, dependsOn: classes) {
    archiveBaseName = 'besu-verkle.trie'
    classifier = 'sources'
    from sourceSets.main.allSource
  }

  task javadocJar(type: Jar, dependsOn: javadoc) {
    archiveBaseName = 'besu-verkle.trie'
    classifier = 'javadoc'
    from javadoc.destinationDir
  }

Resolution

The classifier property has been replaced with archiveClassifier to maintain compatibility with the latest version of Gradle. The updated code is as follows:

  task sourcesJar(type: Jar, dependsOn: classes) {
    archiveBaseName = 'besu-verkle.trie'
    archiveClassifier = 'sources'
    from sourceSets.main.allSource
  }

  task javadocJar(type: Jar, dependsOn: javadoc) {
    archiveBaseName = 'besu-verkle.trie'
    archiveClassifier = 'javadoc'
    from javadoc.destinationDir
  }

Impact

This change ensures compatibility with Gradle 9.0 and resolves the build failure issue.
