Multiplayer Template possibly unused variable

[jhanca-robotecai]

The following fix was required on my Ubuntu to build the Multiplayer Template:

diff --git a/Templates/Multiplayer/Template/Gem/Code/Source/Components/NetworkAiComponent.cpp b/Templates/Multiplayer/Template/Gem/Code/Source/Components/NetworkAiComponent.cpp
index d8a7cb49..1865666b 100644

-
     NetworkAiComponentController::NetworkAiComponentController(NetworkAiComponent& parent)
         : NetworkAiComponentControllerBase(parent)
     {

The variable is not always used and clang 14 on my Ubuntu 22.04 can clearly see that:

/devroot/projects/MultiplayerTemplate/Gem/Code/Source/Components/NetworkAiComponent.cpp:19:28: error: unused variable 'SecondsToMs' [-Werror,-Wunused-const-variable]
    constexpr static float SecondsToMs = 1000.f;
