oracledatabase: fix TestAccOracleDatabaseDbServers_basic

[SirGitsalot]

Fixes nightly acceptance test failure for TestAccOracleDatabaseDbServers_basic.

Root Cause & Fix

1. Incorrect Template Variable in ID Construction:
   DataSourceOracleDatabaseDbServersRead in data_source_oracle_database_db_servers.go constructed the resource ID using projects/{{project}}/locations/{{location}}/cloudExadataInfrastructures/{{cloud_exadata_infrastructure_id}}/dbServers.
   The schema field name is cloud_exadata_infrastructure (not cloud_exadata_infrastructure_id). This mismatch caused variable replacement to fail when setting the resource ID.

2. Persist Project in ResourceData:
   Added d.Set("project", project) so that the resolved project is properly stored in schema.ResourceData, ensuring tpgresource.ReplaceVars and subsequent state checks can access the project attribute.
