Validation error in Bark fine_generation_config
Author: manzonif
Pull request: yes

Fix validation error:
ValueError: `do_sample` is set to `False`. However, temperature is set to 0.5 -- this flag is only used in sample-based generation modes. Set `do_sample=True` or unset temperature to continue.

Hey @manzonif 👋 

BARK has different parameterization needs in its fine submodel, @ylacombe is taking care of the appropriate changes.

Setting `do_sample=True` is not the solution, as no sampling is involved. I'm closing the PR as we are discussing solutions internally :)
