Code from roslyn-analyzers is missing PR and commit history

> Would it be possible to add the repository name to the pull request numbers in the commit messages? Or add a "commit migrated from" trailer like in [dotnet/runtime@e8859b4](https://github.com/dotnet/runtime/commit/e8859b43506858f08dc019fc0faa2be7e2ede3b5).

@ViktorHofer I think it was an unfortunate oversight not to include the suggested changes.

As a result, this has led to a significant loss of metadata, all GitHub Issue and Pull Request links from roslyn-analyzers are now permanently broken within the IDE. Unfortunately, there’s no way to recover the original references, since issue and PR numbers collide between repositories.
