chore: Update NlpSentenceChunking constructor parameters to None

The NlpSentenceChunking constructor parameters have been updated to None in order to simplify the usage of the class. This change removes the need for specifying the SpaCy model for sentence detection, making the code more concise and easier to understand.

 ### Extraction strategy: CosineStrategy
 
+So far, the extracted content is just the result of chunking. To extract meaningful content, you can use extraction strategies. These strategies cluster consecutive chunks into meaningful blocks, keeping the same order as the text in the HTML. This approach is perfect for use in RAG applications and semantical search queries.

 `NlpSentenceChunking` uses a natural language processing model to chunk a given text into sentences. This approach leverages SpaCy to accurately split text based on sentence boundaries.
 
 **Constructor Parameters:**
-- `model` (str, optional): The SpaCy model to use for sentence detection. Default is `'en_core_web_sm'`.
