fix: allow hyphens in mailto link auto-detection (bug 20557)

Browse Source 
Modified the regex in web/autolinker.js to explicitly allow hyphens (-) in
the domain part of email addresses, while maintaining the exclusion of
other punctuation. This fixes mailto links like user@uni-city.tld being
truncated at the hyphen.

Fixes #20557
