update dcl version

[modular-magician]

upgrade DCL to v1.55.0 (pending release note writing)

• google_assured_workloads_workload partner fields caused issues in DCL tests, so I did not include samples for them
• we have no google_gke_hub_feature_membership tests

Release Note Template for Downstream PRs (will be copied)

assuredworkloads: added `enable_sovereign_controls`, `partner`, `partner_permissions`, `violation_notifications_enabled`, and several other output-only fields to `google_assured_workloads_workloads`

containeraws: added `admin_groups` to `google_container_aws_cluster`

containerazure: added `admin_groups` to `google_container_azure_cluster`

gkehub: added `metrics_gcp_service_account_email` to `google_gke_hub_feature_membership`
