Private contributions not being counted

### Describe the bug

The numbers mentioned in this link are very much lower than the numbers in the user's profile

https://github-readme-stats.vercel.app/api?username=xxshubhamxx&show_icons=true&theme=radical&count_private=true

github.com/xxshubhamxx

### Expected behavior

The number of private commits / PRs / contributions should be updated in the count here: https://github-readme-stats.vercel.app/api?username=xxshubhamxx&show_icons=true&theme=radical&count_private=true

This one shows correct data: https://camo.githubusercontent.com/cab836d5e7fbedcef832da26943f12207e9f1a318bd5e409bc381db236c5a26b/68747470733a2f2f6769746875622d726561646d652d73747265616b2d73746174732e6865726f6b756170702e636f6d2f3f757365723d78787368756268616d78782673686f775f69636f6e733d74727565267468656d653d7261646963616c

### Additional context

_No response_

Reproduce the reported GitHub Readme Stats API URL with count_private=true and compare its private commits, PRs, and contributions with the user's profile and linked reference output. No source file or test is named, so trace the API's JavaScript counting path; done means the private totals match the expected profile data and the behavior is covered by a regression test.
