Add auto github release workflow

[saratvemulapalli]

Is your feature request related to a problem?

As part of OpenSearch releases, opensearch-build pushes a tag for the release commit.
But publishing a github release based on the tag is manual.

What solution would you like?

We've added this workflow[1] in OpenSearch which publishes github releases automatically when a tag is pushed.

Add this workflow to all repos releasing software in the project.
See example: https://github.com/opensearch-project/OpenSearch/blob/main/.github/workflows/auto-release.yml
Example Release: https://github.com/opensearch-project/OpenSearch/releases/tag/2.5.0

The feature is added in #1436

Looks like the workflow is failing: The notes are not in the right format.
https://github.com/opensearch-project/observability/actions/runs/4318116929/jobs/7536017277

Run ncipollo/release-action@v1
Error: Error undefined: ENOENT: no such file or directory, open 'release-notes/opensearch-observability.release-notes-test-release-automation.md'

i think it's expected, the failed action was triggered by tag test-release-automation, which is not a release tag. there's no clear pattern (e.g. v* like in ODFE) to match a release tag so currently all tags would trigger the workflow
