Underscore not detected at end of link

[Dsinghbailey]

Marked version:
^4.2.12

Describe the bug
Marked doesn't detect ending underscores in links

https://twitter.com/madebynelson_ is detected as "https://twitter.com/madebynelson"

To Reproduce
Steps to reproduce the behavior:
marked.parse(DOMPurify.sanitize('https://twitter.com/madebynelson_')

Expected behavior
I expect link to render with ending underscore, especially if there are no previous underscores

This is the way it is supposed to work to follow the GFM spec:

Trailing punctuation (specifically, ?, !, ., ,, :, *, _, and ~) will not be considered part of the autolink, though they may be included in the interior of the link

And just so you know, you should sanitize the output of marked not the input.

- marked.parse(DOMPurify.sanitize('https://twitter.com/madebynelson_'))
+ DOMPurify.sanitize(marked.parse('https://twitter.com/madebynelson_'))
