opensea-scraper: [BUG] `offersByScrolling()` and `offersByScrollingByUrl()` not properly working

I noticed that the function offersByScrolling() and offersByScrollingByUrl() is not working properly. Most of the offers are not scraped (a lot of them are skipped for some reason, approximately 75% of the offers are not saved). This leads to the function being stuck for a long time, as it takes a lot longer to scrape the desired amount of offers when 75% of the offers are not scraped.
