fix: improve handling of italics in the presence of links

[KTibow]

Please describe the changes this PR makes and why it should be merged:
The underscore matcher already has (?<!<a?:.+|https?:\/\/\S+), which prevents escaping underscores in emojis, animated emojis, and links (from the https to the first whitespace character).
This PR makes sure asterisks aren't escaped in links either. Fixes #11063.

This fixes that but opens another can of worms (which also is an issue with underscore formatter then). The following markdown <http://*.example.com/globber/*>*Hi* is valid and renders as

But because there is no space between the > and the * your PR would escape it to not be italic Hi anymore.

Do you mean that this PR would fail to escape the italics, introducing new problematic behavior? That's fair, I'll see what I can do about that.
