I’m afraid I don’t... As you said yourself, the repository is private, so if you’ve been removed from it, github disregards all your contributions to it.
However, you can keep contributing open source code! It’s a great way to learn, and it won’t be removed from your list of contributions, only if the project is deleted (but your Fork will stick). Remember, quantity of contributions is not a metric for software quality or for Skill from the programmer, for example, I can do 5000 useless commits, while someone else can solve a major problem in just 1.
A good programmer is not the one who has more contributions, but the one who knows what he is doing and likes what he does.
Welcome to Stackoverflow PT!
It was before the commits, even with private details to the collaborators, appeared on my github. Appeared there to people so-and-so made 100+ contributions in private repository. However since my removal from the repository this has disappeared from my profile for both me and people. I just wanted it to show up back this, because my git at the time ta reset already q was my first stage :)
