fix: use snake_case in gateway update encoder for routing_mode

[vr-ibm]

Fixes hashicorp/terraform-provider-google#27893

Fixes d.Get("routingMode") → d.Get("routing_mode") in the Gateway update encoder template. The camelCase key returns nil from Terraform's schema, which overwrites the correctly-built value and silently drops routing_mode updates for SECURE_WEB_GATEWAY resources.

Details

• Fixes snake_case typo in mmv1/templates/terraform/update_encoder/network_services_gateway.go.tmpl
• d.Get("routingMode") → d.Get("routing_mode") so the field value is correctly force-sent on update
