fix: update laserstream dep to fix connection leak

[thlorenz]

Summary

Update helius-laserstream dependency to a version that fixes the gRPC connection leak.
The upstream fix ensures that when a StreamHandle is dropped, the underlying gRPC connection is properly
aborted via a watch channel close signal, preventing leaked connections from accumulating.

Details

The helius-laserstream git dependency branch was changed from v0.2.2-magicblock to v0.2.2-magicblock+conn-fix.
The upstream fix (in laserstream-sdk) adds a watch::Sender<bool> to StreamHandle whose
Drop impl signals the background stream task to shut down gracefully. This prevents orphaned
gRPC connections when the handle goes out of scope.
