README: make it clear this health panel is about check Laravel apps only

[thomasleveil]

Well, I must have been misleaded by the shinny screenshots. I first thought this was a monitoring panel (built with Laravel) to monitor any service (not related to any Laravel app).

I hope this change in the description sentence will help others that stumble upon this doc understand it all about monitoring one Laravel app ;)

Well, not really. You can pretty much monitor anything, you just have to know to how to configure it, usually just creating .yml files. But yes, some of the aspects of an app are hard to monitor if Health are not inside the app itself, like if the app cache system is working fine, but we can still check if Redis is ok, and is connectable, even if it's not on the same app, or even the same host, because Redis is a service connectable from anywhere. Here are the current resource checkers divided:
