feat: add flag to control whether to preserve additional links in the description

[Ayaa17]

Each news item’s description may contain additional related news titles and links. A flag is introduced to control whether these extra links should be preserved, with the default behavior set to false.

sample code

google_news = GNews(des_keep_url=True) # or False
top_news = google_news.get_top_news()
print(top_news[0]['description'])

des_keep_url is True output:
