Adding Perplexity extra and deprecating the community version of ChatPerplexity (#30649) 
Plus, some accompanying docs updates

Some compelling usage:

```py
from langchain_perplexity import ChatPerplexity


chat = ChatPerplexity(model="llama-3.1-sonar-small-128k-online")
response = chat.invoke(
    "What were the most significant newsworthy events that occurred in the US recently?",
    extra_body={"search_recency_filter": "week"},
)
print(response.content)
# > Here are the top significant newsworthy events in the US recently: ...
```

Also, some confirmation of structured outputs:

```py
from langchain_perplexity import ChatPerplexity
from pydantic import BaseModel


class AnswerFormat(BaseModel):
    first_name: str
    last_name: str
    year_of_birth: int
    num_seasons_in_nba: int


messages = [
    {"role": "system", "content": "Be precise and concise."},
    {
        "role": "user",
        "content": (
            "Tell me about Michael Jordan. "
            "Please output a JSON object containing the following fields: "
            "first_name, last_name, year_of_birth, num_seasons_in_nba. "
        ),
    },
]

llm = ChatPerplexity(model="llama-3.1-sonar-small-128k-online")
structured_llm = llm.with_structured_output(AnswerFormat)
response = structured_llm.invoke(messages)
print(repr(response))
#> AnswerFormat(first_name='Michael', last_name='Jordan', year_of_birth=1963, num_seasons_in_nba=15)
```
