say one thing with ElevenLabsTTSService doesnt work anymore

[durandom]

I replaced the CartesiaTTSService with ElevenLabsTTSService in the https://github.com/pipecat-ai/pipecat/blob/main/examples/foundational/01-say-one-thing.py example, but that doesnt work anymore with 0.0.43

Here's some logging output.
