Autolink doesn't handle trailing underscores in links

[liamwhite]

simple example:

$ target/debug/comrak -e autolink <<< "https://x.com/test_"
<p><a href="https://x.com/test">https://x.com/test</a>_</p>

This is intentional and unlikely to change as it corresponds to GitHub's own logic; see: https://x.com/test_

Should it maybe be an option/plugin to include them and only stop autolink on trailing punctuation and whitespaces?

It might be good to do in Discord flavor since that is the behavior there. I will close this and potentially work on that later.
