fix(github-prs): prevent preloading of PRs currently under review (#1006)

- Updated logic to skip PRs that are currently being reviewed when determining which PRs need preloading.
- Enhanced condition to only fetch existing review data from disk if no review is in progress, ensuring that ongoing reviews are not overwritten by stale data.
