fix(chatterbox): pin omegaconf in every profile requirements file

The previous pin in requirements.txt was ineffective: installRequirements
runs a separate `pip install --requirement` per file, so resolution does
not carry over to the per-profile file where chatterbox-tts is declared.
With chatterbox-tts's unpinned `omegaconf` dep, pip backtracked through
1.x sdists into ruamel.yaml<0.15, whose Python-2-era setup.py fails on
Python 3.10+.

Pin omegaconf==2.3.0 next to chatterbox-tts in every profile file
(matches what upstream chatterbox uses). Drop the dead pin from
requirements.txt.
