Improve docs related to Crawl4AI

[vanetreg]

On page:
https://docs.phidata.com/tools/crawl4ai
specify what max_length means: chars, words or tokens ( I suppose chars but not sure )

---

I have a weird experience:
phidata: v2.7.6
crawl4ai: v0.4.246

Pls. note I set in example code max_length to 4000

agent = Agent(
    model=Ollama(id="llama3.2:latest", host = ollama_base_url, timeout=180),
    tools=[Crawl4aiTools(max_length=4000)],
    show_tool_calls=True
)

but terminal shows 10000 !!
- Running: web_crawler(max_length=10000, url=https://huggingface.co/blog/smolagents)
note I saved the code before running for sure, I even changed the scraped URL to confirm it... :)

EDIT:
note i tested your hackernews.py example
https://github.com/phidatahq/phidata/blob/main/cookbook/async/hackernews.py
and when running it showed:
Running: get_top_hackernews_stories(num_stories=100)
while 10 was set in the code, so it is the 2nd instance of the same weird stuff.

Hey @vanetreg you are correct. We are trying hard to update our docs and keep up with our development. We will fix this soon enough
