Fix SqlClientAttributesExtractor to capture network.type unconditionally

Changed InternalNetworkAttributesExtractor initialization to always capture
protocol attributes (network.type, network.transport, etc.) by passing true
instead of SemconvStability.emitOldDatabaseSemconv().

network.type is a stable attribute that should always be captured for database
spans, not just when old database semconv is enabled.

This fixes Cassandra and R2DBC tests that expect network.type to be 'ipv4' or 'ipv6'.
