Fix API calls failing because of secondary api limits

[jeetchoudhary]

Issue: After upgrading GitHub Enterprise Server (GHES) from version 3.9 to 3.11 and 3.12, we encountered issues with failing API calls during Git search (and other)operations. Further investigation revealed that the newer GHES versions consume more CPU resources, leading to secondary rate limits being reached more frequently. Below is a quote from GitHub Enterprise Support:
"Customers planning to upgrade to GitHub Enterprise Server (GHES) version 3.11 or higher should be aware of the potential for increased CPU utilization. If a system's peak CPU usage is already high, typically above 65-70%, it is strongly advisable to scale up the server resources before upgrading. This is to accommodate the additional load from new features and improvements that are part of the latest releases."

Moreover, we realized that GitHub does not guarantee the presence of the Retry-After header. However, the gh-limited-by header is included in the response when the error is due to rate-limiting

We got ourselves unblocked after making this change. I see the issue is reported by another user here as well
#1805

Fix: The intention is not to change any existing functionality. So ended up adding an additional optional check, so that the API client can wait for another minute before retrying the API call if either of the headers are present. With the new change the client will execute this block https://github.com/hub4j/github-api/blob/main/src/main/java/org/kohsuke/github/AbuseLimitHandler.java#L82-L93 which is not happening right now

Needs test to cover the new functionality. Otherwise looks good.
