The username, group, and netgroup patterns in the sudoers syntax file used \l\+ which only matched pure lowercase letters. Linux usernames commonly contain hyphens, digits, and underscores (e.g. www-data, deploy01, test_user), so these weren't getting highlighted.

Changed \l\+ to \l[-a-z0-9_]* in all 12 affected patterns (UserName, Group, UserNetgroup across all four contexts).

Closes #18963

@e-kwsm did not re-act to the original issue, so I'll merge it and leave a not in the syntax script. Thanks
