Validation error in Bark fine_generation_config

[manzonif]

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 :)
