NLTK data is getting re-downloaded each new post

Context

It appears that the nltk data is getting re-downloaded (or at least attempted) each time a new post is created.
I'm not sure why it's trying to download the data so many times?

This is because I call the download function inside of the function that preprocesses text. Not desireable, so if you'd like to open a PR with a fix, go ahead!

def preprocess_text(text: str) -> str:
    """
    Preprocess the input text by applying text preprocessing steps
    """
    # Convert the text to lowercase
    text = text.lower()
    # Remove any leading or trailing whitespace
    text = text.strip()
    # Remove punctuation marks
    text = text.translate(str.maketrans("", "", string.punctuation))
    # Remove numbers
    text = re.sub(r'\d+', '', text)
    # Remove extra whitespaces
    text = re.sub(r'\s+', ' ', text)
    # Remove stopwords
    nltk.download('stopwords') # This is triggering the download
    stop_words = set(stopwords.words('english'))
    text = ' '.join([word for word in text.split() if word not in stop_words])
    return text
    ```
