Release new llama-cpp-haystack version

[awinml]

Describe the bug
The model_path parameter was renamed to model in #243. This change is not reflected on the current llama-cpp-haystack version on pypi.
The documentation showcases the new API with model, causing a mismatch.

To Reproduce
To download the model:

curl -L -O "https://huggingface.co/TheBloke/OpenHermes-2.5-Mistral-7B-GGUF/resolve/main/openhermes-2.5-mistral-7b.Q4_K_M.gguf"

from haystack_integrations.components.generators.llama_cpp import LlamaCppGenerator

generator = LlamaCppGenerator(
    model="openhermes-2.5-mistral-7b.Q4_K_M.gguf", 
    n_ctx=512,
    n_batch=128,
    generation_kwargs={"max_tokens": 128, "temperature": 0.1},
)
generator.warm_up()
prompt = f"Who is the best American actor?"
result = generator.run(prompt)

Describe your environment (please complete the following information):

• OS: Linux
• Haystack version: haystack-ai==2.0.0b8
• Integration version: llama-cpp-haystack==0.2.1
