Oracle fails with `ORA-12154: TNS:could not resolve` if not overriden

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

```csharp
var oracle = builder
.AddOracle("oracle")
.WithImage("database/free", "23.8.0.0")
.WithImageRegistry("container-registry.oracle.com")
.WithLifetime(builder.GetLifetime());
```

throws Oracle.ManagedDataAccess.Client.OracleException (0x80004005): ORA-12154: TNS:could not resolve the connect identifier specified

, when hacked using

```csharp
var oracle = builder
.AddOracle("oracle")
.WithImage("database/free", "23.8.0.0")
.WithImageRegistry("container-registry.oracle.com")
.WithLifetime(builder.GetLifetime());

var oracleDb = oracle.AddDatabase("billing-oracle", databaseName: "FREE");

// Fix: Oracle connection string needs full TNS descriptor with SERVICE_NAME
// ODP.NET requires DESCRIPTION format because EZCONNECT is not enabled by default
// Format: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host)(PORT=port))(CONNECT_DATA=(SERVICE_NAME=FREE)))
var oracleConnStr = builder.AddConnectionString(
"oracledb-fixed",
ReferenceExpression.Create(
$"user id=system;password={oracle.Resource.PasswordParameter};"
+ $"data source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST={oracle.Resource.PrimaryEndpoint.Property(EndpointProperty.Host)})(PORT={oracle.Resource.PrimaryEndpoint.Property(EndpointProperty.Port)}))(CONNECT_DATA=(SERVICE_NAME=FREE)))"
)
);

database = oracleConnStr;
```

referencing `oracleConnStr` gives correct results

### Expected Behavior

```csharp
var oracle = builder
.AddOracle("oracle")
.WithImage("database/free", "23.8.0.0")
.WithImageRegistry("container-registry.oracle.com")
.WithLifetime(builder.GetLifetime());
```

should work without hacks
