Sync web-scraping-with-scrapy-and-mongodb with the maintenance update of "Web Scraping With Scrapy and MongoDB"

- Replace the spider's def start_requests(self) with async def start(self);
  Scrapy removed Spider.start_requests() in 2.16.0, so on current Scrapy the
  method was never called and the errback on the initial request was silently
  dropped.
- Re-pin requirements.txt to the tutorial's new dependency set
  (Scrapy 2.18.0, pymongo 4.17.0, Python 3.14).
