Does not recognize when it has access through an organization

For some reasons[^1] my clone of cpython is not a repository on my user but on the https://github.com/chrysn-pull-requests, which is technically an organization.

I've gone through the initial setup steps of the blurb-it online app, and as part of that allowed it access to my repository https://github.com/chrysn-pull-requests/cpython, but after returning to https://blurb-it.herokuapp.com/, I still just see "Please install the blurb-it GitHub App, and enable it on your CPython repository." (Then when I follow the install link, GitHub shows it as already installed for chrysn-pull-requests and gives me a link to configure it).

Maybe this is just a recognition problem in the start page, and I can jump to the actual app with the right deep link?

[^1]: Irrelevant to this PR, but if curious: I dislike how GitHub mangles the terms "forking" and "creating a branch", and thus keep a separate group of repositories that I do not intend to fork, but just have branches on.

Inizia dalla pagina iniziale dell’app online blurb-it e riproduci la configurazione con la GitHub App installata per l’organizzazione chrysn-pull-requests e il relativo repository cpython. Traccia il modo in cui la pagina verifica l’accesso al repository; il lavoro è completato quando viene riconosciuto un repository di proprietà di un’organizzazione oppure l’utente riceve un deep link funzionante all’app.
