function tests in recent PRs (#772, #776, #777, #778, #780, #784) failed because of a llama_cpp_python version upgrade.

• we need llama_cpp_python==0.2.55 to make the current functional test passes, which doesn't work for 0.2.58.
• with 0.2.58, lab serve doesn't return the same different error to client side therefore https://github.com/instruct-lab/cli/blob/main/scripts/functional-tests.sh#L114-L120 fails
  • with a quick check, it seems that there is some error on the llama_cpp_python side that the expected message doesn't pass to the client side. so maybe this will be fixed in the future

I think it's fair to either

• fix the version to 0.2.55, or
• disable that particular check for now
