Make the trajectory of the projectile straight(When looking down and up)

This is primarily a fix needed for mace PvP.

Currently, each PvP server is resolving this issue by installing plugins or mods, but there should be little downside to incorporating it as a vanilla feature.

Changing the throwing direction might affect some devices, but this shouldn't be a problem.

Conversely, it would be ideal if dispensers fired mace with a slightly random trajectory.

While server administrators might think they can simply install mods, the problem is that changing vanilla behavior might make some players perceive it as a form of cheating. While this might not be the case within the PvP community, I'm somewhat concerned about how general players might perceive it. Therefore, implementing it as a vanilla feature would allow for PvP without such concerns.
