ICall crash with 5 method args limit

[chippmann]

We have a method args limit of 5 which we enforce with:

#ifdef DEBUG_ENABLED
    JVM_CRASH_COND_MSG(args_size > VARIANT_ARG_MAX, vformat("Cannot have more than %s arguments for method call.", VARIANT_ARG_MAX));
#endif

This leads to api call to fail:

ERROR: Godot-JVM: Cannot have more than 5 arguments for method call but tried to call method "ENetMultiplayerPeer::create_client" with 6 args

It seems godot changed the max to 8 a while ago: godotengine/godot#54188
