Disallowing certain include types

[countless-integers]

Right now, adding includes to query params allows for "count" and "exists" variations of them. E.g.

$posts = QueryBuilder::for(Post::class)->allowedIncludes(['user']);

would accept query params like include[]=user, include[]=userCount or include[]=userExists. This behaviour seems to be a consequence of this bit of code in AllowedInclude.

What I'd like to achieve is to prevent users from being able to use userCount and userExists include values (or at the very least, hide those options from the exception message thrown in AddsIncludesToQuery.

I've somewhat hacked my way to that result by setting suffix values for those parameters to an empty string (e.g. for exists_suffix), but this feels a bit brittle.

What would you advise for me to do instead to get that functionality of disallowing those include types?
