fix: use modernized and standardized OpenTelemetry when tracing

This change modernizes trace span attributes by using OpenTelemetry's semantic conventions that are standardized and allow for much better common ground adoption by broader systems, even more as Google Cloud Tracing & Monitoring pushes towards OpenTelemetry more. With this change we've made the replacement of these fields, directly with imports from `opentelemetry.semconv.trace.SpanAttributes`, as: * "db.type" => DB_SYSTEM aka "db.system" * "db.url" => DB_CONNECTION_STRING aka "db.connection_string" * "db.instance" => DB_NAME aka "db.name" * "net.host.name" => NET_HOST_NAME aka "net.host.name" While here, also updated opentelemetry-(api, sdk) dependencies to use versions "1.25.0", then opentelemetry-(instrumentation) to "0.46b0" Fixes googleapis#1170 Fixes googleapis#1173
