Fix redirect loop in Gitea rate limit

What does this MR do and why?

The current implementation applies a rate limit to the status endpoint to limit repository list fetches from Gitea per minute.

This change increases the rate limit threshold to prevent regular users from being rate limited during normal usage.

This resolves the infinite redirect issue and improves the overall user experience.
