139448: release: generate cloud-only metadata artifact r=rail a=rail

Previously, we needed to crawl the build log in order to find the cloud-only build metadata, such as version and cloud-only release number.

This PR adds a step to generate a metadata file with basic information.

Fixes: RE-783
Release note: None
