Contributors sidebar widget shows a stale contributor no longer in any commit

Body

Hi there,

The small "Contributors" widget on my repository's main page (top-right sidebar) is showing an outdated contributor who no longer appears in any commit's author or committer field.

Repository: https://github.com/GianMandara/Sistema-Professor-V2

What I checked:

git log --format="%an <%ae> | %cn <%ce>" for every commit in the repo shows only one author/committer across the entire history.
The full contributors graph (https://github.com/GianMandara/Sistema-Professor-V2/graphs/contributors) already correctly shows only one contributor.
I pushed an empty commit a few days ago specifically to try to force a stats recompute — it fixed the full graphs page, but the small sidebar widget on the repo's main page is still showing the stale second contributor.
This looks like the small sidebar widget is served from a separate cache than the full /graphs/contributors page, and that cache hasn't been invalidated.

Could someone help trigger a recompute of that specific cache, or let me know if this is expected to resolve on its own over time?

Thanks!
