Hey thanks for your PR.

After performing some automated testing on additional recipe pages, it appears that the updated userAgent works better on some pages. Importantly, I did not find a single page where the previous userAgent worked but the updated one did not. Therefore, I will approve the changes. However, it should be noted that this is only used as a fallback userAgent if importing the user agent provided from the scraper library fails. Usually, Mealie would scrape using the user agent below, with version being the recipe_scrapers version.

"User-Agent": f"Mozilla/5.0 (compatible; Windows NT 10.0; Win64; x64; rv:{__version__}) recipe-scrapers/{__version__}"

Also it seems like scraping from the foodnetwork.com is working again with the current setup which you can verrify on the demo.
