PHP deprecation warning

Hi,

We’re using WPMDB and Query Monitor, and I’ve noticed that the latter is warning of deprecated PHP in WPMDB. It’s returning the following warning:

DeliciousBrains\WPMDB\Container\DI\Container::__construct(): Implicitly marking parameter $wrapperContainer as nullable is deprecated, the explicit nullable type must be used instead

It doesn’t seem super-critical, but it might be something to look at in future updates. Thanks!
