Gets the top-level Bicep parameters emitted for secret/parameter values referenced by container environment variables. Secret sources are declared `@secure()` so their values are supplied at deploy time via `rad deploy --parameters` rather than inlined.

```csharp
public List<ProvisioningParameter> Parameters { get; }
```
