[ENHANCEMENT] opensearch.opensearchplugin add groupID field to org.opensearch.plugin

[prudhvigodithi]

Description

The configuration modification for the gradle plugin opensearch.pluginzip to make sure the groupId is added as org.opensearch.plugin to the publication pluginZip inside the build.gradle file.

Related META issue

Part of: opensearch-project/opensearch-build#2521
From solution: opensearch-project/OpenSearch#3692

Current Behavior

The opensearch.opensearchplugin uses the default setting for groupId as org.opensearch.plugin, this when extended with open source community, it should be feasible to ammend the groupId as per required, hence for opensearch plugins the groupId should be mentioned as org.opensearch.plugin to make sure the opensearch plugins are published to this groupID and for other generic uses this can be extended to the custom groupId.

Expected Behavior

Once the groupId is added as org.opensearch.plugin to the publication pluginZip inside the build.gradle file, the plugin zips should continue to be published to the existing groupID.

Proposed solution

We'll pick this up before 2.4 release.

@prudhvigodithi we just need to add a groupID: org.opensearch.plugin here right?
We don't need to change project.group here? Asking just for confirmation due to this.

Also, anything to verify/test here?

FYI: @sricharanvuppu will be working on this.
