I see that `quarto render` automatically checks for broken internal links (#41), which is super helpful. It would be great, especially for websites, to also check for broken external links.

Someone was recently reading my blogdown blog (which I am porting to Quarto) and they mentioned that they had found a bunch of dead links, especially URLs imported into Reference sections from `.bib` files. I can check for this manually  after publishing using https://www.deadlinkchecker.com/website-dead-link-checker.asp, but it would be nice to fix dead links before publishing, similar to how `urlchecker::url_check()` works for R packages.
