feat(fetch): added playwright support

[PeriniM]

Now the html pages will be fetched using Playwright.
If after using the browser in headless mode you don't get results, you can set the headless flag to False in the graph config.

graph_config = {
    "llm": {
        "model": "groq/gemma-7b-it",
        "api_key": groq_key,
        "temperature": 0
    },
    "embeddings": {
        "model": "ollama/nomic-embed-text",
        "temperature": 0,
        "base_url": "http://localhost:11434",  # set ollama URL arbitrarily
    },
    "headless": False
}
