fix: bump OTel and traceloop versions

[LucasAlvesSoares]

Description

Upgrade traceloop-sdk and OpenTelemetry dependencies

• traceloop-sdk: 0.54.0 → 0.61.0
• opentelemetry-api / opentelemetry-sdk: >=1.28.0 → >=1.42.1
• opentelemetry-exporter-otlp-proto-grpc / opentelemetry-exporter-otlp-proto-http: 1.41.0 → 1.42.1
• Removed wrapt<2 constraint: the traceloop-sdk upgrade resolves the upstream incompatibility with wrapt 2.x that previously caused the LangChain instrumentor to fail at import time
