[FEAT]: Enumerationize GitHubCommitFile.Status

[zhiliangpt]

Describe the need

Inside:

    [SuppressMessage("Microsoft.Naming", "CA1702:CompoundWordsShouldBeCasedCorrectly")]
    public GitHubCommitFile(string filename, int additions, int deletions, int changes, string status, string blobUrl, string contentsUrl, string rawUrl, string sha, string patch, string previousFileName)
    {
        Filename = filename;
        Additions = additions;
        Deletions = deletions;
        Changes = changes;
        Status = status;
        BlobUrl = blobUrl;
        ContentsUrl = contentsUrl;
        RawUrl = rawUrl;
        Sha = sha;
        Patch = patch;
        PreviousFileName = previousFileName;
    }

... we have GitHubCommitFile.Status as string equals "added", "modified", "removed", "renamed", etc.

These Statuses do not co-exist for a given commit, so it would be ideal to handle them as enumerations to minimize errors in the code with more elegance.
