Ignore union-attr mypy errors in scraper modules

This is primarily done for one widespread set of noisy (usually false positive) errors in particular: AbstractScraper.soup.find(...) returns {Tag | NavigableString | None}, and we often call find / find_all on the results of that.  NavigableString doesn't provide those methods, and having to isinstance check on every find call would be annoying
