Manually Trigger Preview Environments with Create On Demand Feature

The updated Preview Environment feature offers developers enhanced flexibility and control by allowing them to create on-demand replicas of production environments directly from Pull Requests/Merge Requests, optimizing testing and validation processes. Previously, preview environments were automatically generated for every pull request, which often led to unnecessary previews. The new feature introduces a "Create on Demand" option, enabling developers to decide when to trigger these environments, thereby streamlining workflows and reducing unnecessary usage. This change is designed to fit seamlessly with different Git providers, enhancing the software development process by empowering developers to manage their workflows more efficiently and effectively.
