Remove optional support for non-lazy loading of types

Lazy loading has been introduced in 2.0.0 (2019-08) and has
been enabled by default in 8.0.0 (2021-11).

From now on the type loader is always used when resolving
types and the impact mostly means that you can't have
types registered using an alias different from their
name.

As can be seen by th commit, this reduces complexity and
maintenance overhead of the library.

+## Breaking changes
+### Removed
+- Remove support for eager loading (=non-lazy loading) of types\
+  Lazy loading has been introduced in 2.0.0 (2019-08) and has been made the
+  default since 8.0.0 (2021-11).\
+  The practical impact is that types are always going to be resolved using a
+  type loader and therefore cannot use aliases anymore. Types and their type
+  name have to match.

 ## Performance considerations
 
-### Lazy loading of types
-
-Lazy loading of types is a way of improving the start up performance.
-
-If you are declaring types using aliases, this is not supported and you need to
-set `lazyload_types` set to `false`.
-
-#### Example of aliasing **not** supported by lazy loading
-
-I.e. you cannot have a query class `ExampleQuery` with the `$name` property
-`example` but register it with a different one; this will **not** work:
-
-```php
-'query' => [
-    'aliasedExample' => ExampleQuery::class,
-],
-```
-
 ### Wrap Types
 
 You can wrap types to add more information to the queries and mutations. Similar as the pagination is working you can do the same with your extra data that you want to inject ([see test examples](https://github.com/rebing/graphql-laravel/tree/master/tests/Unit/WithTypeTests)). For instance, in your query:
