dynamic_missions/Hooks.cpp invalid #include, does not compile

[PlaYsiADiscovery]

Using what looks like an older style:
#include "../flhookplugin_sdk/headers/FLHook.h"

Looking at every other project it should be:
#include <FLHook.h>

Most importantly, does not compile even when manually adding reference and other attempts at wrangling.

This is a really old plugin from the original era that I believe we never updated as DiscoveryFL never made use of it. It's still in the repository mostly for historical purposes.
