[BUG]: Getting issue by issue number panics if there is a label present on issue

[kfcampbell]

What happened?

I'm using the following code snippet:

    client, err := pkg.NewApiClient(
        pkg.WithUserAgent("my-user-agent"),
        pkg.WithRequestTimeout(5*time.Second),
        pkg.WithBaseUrl("https://api.github.com"),
        pkg.WithTokenAuthentication(os.Getenv("GITHUB_TOKEN")),
    )

    if err != nil {
        log.Fatalf("error creating client: %v", err)
    }

    queryParams := &abs.DefaultQueryParameters{}
    requestConfig := &abs.RequestConfiguration[abs.DefaultQueryParameters]{
        QueryParameters: queryParams,
    }

    issue, err := client.Repos().ByOwnerId("hilli").ByRepoId("issue-test").Issues().ByIssue_number(1).Get(context.Background(), requestConfig)
    if err != nil {
        log.Fatalf("error getting issue: %v", err)
    }
    fmt.Printf("issue: %+v", issue)

This code panics, since https://github.com/hilli/issue-test/issues/1 has a label on it. There's some kind of issue going on in which labels aren't being deserialized correctly. See a debugging screenshot in which we attempt to force unwrap a nil value for the label:

The final panic is:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x9e6418]

By contrast, the same request to https://github.com/kfcampbell/a-repo/issues/1 succeeds, as it doesn't have any issues in place:

Note that label IDs have already been updated to int64 from what I can tell.
