Describe the bug
When reproducing the code with telemetry (docs/source/en/tutorials/inspect_runs.md). There is an error from the telemetry with the message format.

Code to reproduce the error

from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor

from openinference.instrumentation.smolagents import SmolagentsInstrumentor
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.trace.export import ConsoleSpanExporter, SimpleSpanProcessor

endpoint = "http://0.0.0.0:6006/v1/traces"
trace_provider = TracerProvider()
trace_provider.add_span_processor(SimpleSpanProcessor(OTLPSpanExporter(endpoint)))

SmolagentsInstrumentor().instrument(tracer_provider=trace_provider)

Error logs (if any)
Invalid type dict in attribute 'llm.input_messages.0.message.content' value sequence. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or None

Expected behavior
The message text property is logged
