runtime(sudoers): highlight usernames with hyphens, digits, underscores
The username/group/netgroup patterns used \l\+ which only matched
lowercase letters. Linux usernames commonly contain hyphens, digits,
and underscores (e.g. www-data, deploy01, test_user).
Update the pattern to \l[-a-z0-9_]* to allow matching the additional
characters "-_" and numbers.
fixes: #18963
closes: #19396
