Incorrect warning about redeclaration of function parameter as static variable about phpcs-variable-analysis

😩 You're right. Detecting static declarations is a lot harder than it looks, I guess. Here's a minimal test case I came up with which actually produces a bunch of weird errors:

function function_with_static_closure_inside_array_map($account, $getTeamsByUserQuery) {
  $developer_team_ids = array_map(
    static function (GroupInterface $group) {
      return (int) $group->id();
    },
    ($getTeamsByUserQuery)((int) $account->id())
  );
  return $developer_team_ids;
}

 2 | WARNING | Unused static variable $account.
 2 | WARNING | Unused static variable $getTeamsByUserQuery.
 7 | WARNING | Redeclaration of function parameter $getTeamsByUserQuery as static variable.
 7 | WARNING | Redeclaration of function parameter $account as static variable.

Thanks, this was quick 😉
