Dearrow plugin change

[evaz1995]

Hello,

I noticed that the Dearrow plugin does not properly work when the API for Dearrow throws a 404 error, even when the embedded link is indeed a Youtube video. Hence I am proposing this change: if no title nor thumbnail is provided by the main API, the thumbnail API is used instead, which should provide a response for all YouTube videos unless the API is down.

Hi!
The way the plugin currently works is that it will only replace the thumbnail if the replacement has at least one upvote. I think this was done to only use manually created replacements.
I am not opposed to also using automatic replacements but I think many people probably don't want these. We should make it configurable with a new setting, defaulting to false

Besides that, it'd be much better if you refactored your changes so that it won't use a failed request's response as if it succeeded, that's asking for trouble! Something like the following would be much more robust

const res = await fetch(normalApi);
if (res.ok) {
	// existing code ...
} else if (settings.store.useAutomaticThumbnails) {
	const res = await fetch(thumbnailApi);
	// ...
}

Besides that I do like this idea, so thank you!
