Description
nginx version: 1.22.0
otel-webserver-module: v1.0.3
nginx log：
[libprotobuf ERROR /grpc/third_party/protobuf/src/google/protobuf/wire_format_lite.cc:577] String field 'opentelemetry.proto.common.v1.AnyValue.string_value' contains invalid UTF-8 data when serializing a protocol buffer. Use the 'bytes' type if you intend to send raw bytes.

Research direction
Start by reproducing the logged invalid UTF-8 serialization error with nginx 1.22.0 and otel-webserver-module v1.0.3, then trace how the module handles string fields before protobuf serialization. Done means the affected input is handled without this error, with the behavior verified against a regression case.
