Enhanced Changelog URLs and Project Slugs

In this update, we have implemented a new URL structure for the changelog pages, transitioning to a format that includes both the owner and repository slugs. This enhancement allows for more descriptive and meaningful URLs, making it easier for users to navigate and share changelog entries.

Additionally, we have added fields for the owner_slug and repo_slug within the project model. These new fields enable users to customize their changelog URLs, ensuring that they are aligned with their specific project names on GitHub. Existing projects will automatically have these slugs populated based on their GitHub full names, enhancing the overall user experience.

Furthermore, adjustments were made to various views to accommodate these changes, ensuring that links throughout the application reflect the new URL format. This means that anywhere the changelog URL was previously used, it has now been updated, streamlining access to project information.

Thank you for your continued support as we strive to improve your experience!
