Looks like a dup of #716

[prudhvigodithi]

Hey @dblock, since there are two aspects for this maven publish, one for snapshots repo and other for actual release repo, the two repo workflows are not constant, as release repo has more wider process, like pre staging, promoting, signing, additional maven tags and then releasing, so I have created a meta issue #1916 that expands with more details based on the issue #716.
Right now the snapshot zips for maven snapshot repo, does not have an enforced workflow to publish a zip, unlike the actual release repo, so I have separated into two tasks for snapshot plugin zips and release plugin zips and together tracked in #1916.

[prudhvigodithi]

Using the plugin opensearch.pluginzip and with existing CI worflows, the zips will signed and published
Example

Closing this issue as resolved :)
