Support latest Eleven Labs version

[aadya940]

Hello, I'm using both the manim_voiceover and elevenlabs libraries in my python project. However, elevenlabs version I need to use is the default version 1.50.3. However, manim_voiceover requires version 0.2.27. Would it be possible to support the later versions.

I published a new package here for myself:

https://pypi.org/project/manim-voiceover-fixed/
https://github.com/9oelm/manim-voiceover

Won't do a PR here cos I think it's being poorly maintained.
