Fix HookManagerInterface annotation

[ChrisLightfootWild]

Align OpenTelemetry\API\Instrumentation\AutoInstrumentation\HookManagerInterface::hook postHook Closure signature with OpenTelemetry\Instrumentation\hook.

Phan complains in open-telemetry/opentelemetry-php-contrib#269. Upon checking, I think the annotated signature of the post-hook is possibly incorrect?

This is an example of what I am seeing:.

In pre-hook:

src/Hooks/Illuminate/Contracts/Http/Kernel.php:48 PhanTypeMismatchArgumentSuperType Argument 3 ($preHook) is (function) of type Closure(\Illuminate\Contracts\Http\Kernel,array,string,string,?string,?int):array{0:?\Illuminate\Http\Request} but \OpenTelemetry\API\Instrumentation\AutoInstrumentation\HookManagerInterface::hook() takes Closure(null|object|string,array,string,string,null|string,int|null):void|null defined at vendor/open-telemetry/api/Instrumentation/AutoInstrumentation/HookManagerInterface.php:17 (expected type to be the same or a subtype, but saw a supertype instead)

In post-hook:

\OpenTelemetry\API\Instrumentation\AutoInstrumentation\HookManagerInterface::hook() takes Closure(null|object|string,array,mixed,\Throwable|null):void|null defined at vendor/open-telemetry/api/Instrumentation/AutoInstrumentation/HookManagerInterface.php:17 (expected type to be the same or a subtype, but saw a supertype instead

Edit: it was late and I pasted an example of pre-hook instead of post-hook. Both were throwing phan errors.
