Adding a workflow to automatically publish releases after a tag is pushed

[saratvemulapalli]

Signed-off-by: Sarat Vemulapalli vemulapallisarat@gmail.com

Description

Release tags are automatically published by https://github.com/opensearch-project/opensearch-build.
Github releases [1] are not published and are manually published after every release.

This workflow automates publishing github releases.
It automatically includes the release notes.

I've tested this manually on my fork:
Release: https://github.com/saratvemulapalli/OpenSearch/releases/tag/5.4.6
Workflow: https://github.com/saratvemulapalli/OpenSearch/actions/runs/2632146820
