We are in need of a deployment preview workflow for our Uptane repository. This workflow is intended to operate specifically for pull requests, providing our reviewers with a live link to assess and review the proposed changes on our website before finalizing the merge process. The primary objective is to have a system where pull requests can initiate a build on a dedicated path, allowing reviewers to evaluate the results of these changes.

We have a preference for open-source alternatives for deployment and do not wish to rely on third-party services like Netlify for deployment or any paid alternatives. Instead, we are actively seeking open-source alternatives that offer similar functionality, We are open to all suggestions, and if there is a way to achieve this directly through GitHub Pages by creating a custom workflow, that would be highly advantageous.
