feat!: rename CartesiaExperimentalControlsSpeedZero and FallbackAzureVoiceVoiceIdZero modules

Rename two internal enum modules to better reflect their purpose and
align with updated naming conventions. These modules are part of the
public type system and any code referencing them by name will break.

Key changes:
- Rename `Vapi::Types::CartesiaExperimentalControlsSpeedZero` → `Vapi::Types::CartesiaSpeedControlZero`
- Rename `Vapi::Types::FallbackAzureVoiceVoiceIdZero` → `Vapi::Types::FallbackAzureVoiceIdZero`
- Update `CartesiaSpeedControl` and `FallbackAzureVoiceId` union members to reference the new module names
