Add release pages for the next release of OpenSearch with "latest" links.

Is your feature request related to a problem? Please describe.
As a developer I often use the latest build of OpenSearch-min, or a plugin. The URLs are difficult to discover. It was difficult to add an index page because the numbers are changing with every build, but now we have support for "latest" in the URLs.

Describe the solution you'd like
Add a page for the next release(s) that contains:

1. Links to the GitHub release issue, e.g. [RELEASE] Release version 1.3.0 opensearch-build#889.
2. Links to the latest manifests, e.g. https://ci.opensearch.org/ci/dbc/distribution-build-opensearch/1.3.0/latest/linux/arm64/builds/opensearch/manifest.yml
3. Links to some of the typical latest binaries, e.g. x64-min from out the manifest.
4. Latest integration test and performance test results.

This is an interesting idea. Do you see this as extension of the download page or something else entirely?
