<LinkTo> doesn't require @route if @query is provided

Maybe this is a bad practice, but it does actually work despite glint being unhappy.

app/components/sortable-header.hbs:3:5 - error TS2345: Argument of type '{ query: { sortKey: string; }; }' is not assignable to parameter of type 'LinkToArgs'.
  Property 'route' is missing in type '{ query: { sortKey: string; }; }' but required in type 'LinkToArgs'.

  3     <LinkTo @query={{hash sortKey=this.sortKey}}>
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  4       <span class="sortable-header-name">
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
... 
 13       </span>
    ~~~~~~~~~~~~~
 14     </LinkTo>

I can't find docs that validate this, but this issue seems to support this behavior emberjs/ember.js#17963.
