Fix: decode PR list entries individually to skip invalid entries

The previous implementation used Schema.Array(GitHubPullRequestSchema) which
fails the entire decode if any single entry is invalid. This restores the
lenient per-entry behavior where invalid entries are silently skipped,
matching the old parsePullRequestList semantics.
