fix(handlers): restore the group hint's link filter

Replacing is_group(kind) with teloxide's predicates dropped the parentheses:
&& binds tighter than ||, so the branch read as is_group() OR (is_supergroup()
AND has-link) -- a plain group got the hint for any link, supported or not.
The e2e test only covered a group with a supported link (which is true either
way); it now also covers an unsupported link in a group.
