Support `youtube-nocookie.com` in the URL pattern

Since this plugin automatically detects YouTube URLs, it would be great if the link of a video already added from youtube-nocookie.com could be detected!

Hm, I'd want to ponder this one a bit. youtube-nocookie.com is generally only used when you're already the context of embedding a video. Can you tell me a little more about your use case? At first glance it feels a bit niche, and my concern is adding another domain check is a risk for RegExp performance.

Hi @gfscott! I suggested it simply because as YouTube privacy policies and practices worsen every day, I try to always use the most private option by default. Therefore, also when sharing simple YouTube links to people via chat, I always use youtube-noccokie. I think it can be very useful also to click the link from the source code, and have a clean interface.
