chore: bump arsenal to ARSN-572 PoC branch for e2e trace context testing

Temporarily point the arsenal dep at scality/Arsenal#improvement/ARSN-572/trace-context
so we can validate end-to-end trace context propagation from cloudserver
HTTP spans through to the MongoDB oplog on a test cluster. ARSN-572 adds
traceContext plumbing on metadata writes; cloudserver needs no code change
thanks to OTEL async context hooks.

Yarn resolves the branch ref and pins the resolved commit hash in
yarn.lock so installs are reproducible.

Revert to a clean #8.x release tag once ARSN-572 ships.

Issue: CLDSRV-884
