Update reader.py strip html tags from content, example.py

[strueman]

HTML tags were present in content:

The changes made are to reader.py:

1. Added a new line to strip HTML tags from the content field:

content = BeautifulSoup(entry.summary, "html.parser").get_text(strip=True)

2. Modified the extracted_text assignment to use strip=True:

extracted_text = soup.get_text(strip=True)

3. Updated the RedditContent creation to use these new stripped values.
   These changes will remove HTML tags and extra whitespace from both the content and extracted_text fields. The get_text(strip=True) method removes all HTML tags and strips leading and trailing whitespace.
   With these modifications, the output should no longer contain HTML tags in the content and extracted_text fields.

Update example.py

• Replaced 'datetime.utcnow()' as its depreciated

replaced datetime.utcnow() with datetime.now(timezone.utc) as datetime.utcnow() is depreciated and being removed from datetime.
Changes:

#Old:

from datetime import datetime, timedelta
since_time = datetime.utcnow().astimezone(pytz.utc) + timedelta(days=-5)

#New:

from datetime import datetime, timedelta, timezone
since_time = datetime.now(timezone.utc).astimezone(pytz.utc) + timedelta(days=-5)

Just realized that this is probably not needed, my tired brain missed the whole point of extracted_text
