This pull request introduces a normalization function to ensure that the forkedFrom URL for forked repositories is correctly mapped in special cases, specifically for the Linux kernel repository. The normalization logic is added in both the GitHub REST integration use case and the GithubIntegrationService class. This change prevents the system from referencing the GitHub mirror of the Linux kernel and instead maps it to the official kernel.org repository URL.

Normalization of forked repository URLs

• Added a normalizeForkedFrom function in getInstalledRepositories.ts to handle special cases, mapping the Linux kernel GitHub mirror to the official kernel.org URL.
• Updated the parseRepos function in getInstalledRepositories.ts to use the new normalization function when setting the forkedFrom property.

GithubIntegrationService enhancements

• Implemented a static normalizeForkedFrom method in GithubIntegrationService.ts to centralize normalization logic for forked repository URLs.
• Updated repository parent URL handling in GithubIntegrationService.ts to use the normalization method when fetching parent repository information and when constructing repository data. [1] [2]
