'Total PRs Reviewed' is only counting reviews in the past year.

### Describe the bug

This is a continuation of my discussion from 2023 (https://github.com/anuraghazra/github-readme-stats/discussions/3237). There I said my review count was zero, and in that year I had 0 pull requests reviewed. However, currently, in the past year, I have reviewed 2 pull requests and my count of 'Total PRs Reviewed' is two (see picture). I have fetched data from GraphQL, and there it says that in total I have 22 pull requests reviewed. I am using my private Vercel instance.

### Expected behavior

To have 22 pull requests reviewed as that is my total. 2 is only in the past year.

### Additional context

_No response_

Start by tracing the GraphQL data fetch and the code that calculates “Total PRs Reviewed,” then compare the returned lifetime total with the count limited to the past year. Verify the change against the reported values: 22 total reviewed pull requests rather than 2 in the past year.
