Fix attack animation not playing with Yes Steve Model

[Under-estimate]

Yes Steve Model plays attack animation according to the handSwinging variable. Updating it in startUpswing makes the animation work properly.

Relevant issue: #385

Can you help me please, I went to the mod's github page and searched for "startUpswing" but I can't find "player.handSwinging" anymore.

Thank you for the contribution!

This PR is targeting an old game version, whichI have no longer have an active workspace installation of.

The changes look minimal, yet non intuitive.

I would need to spend a decent amount of time to understand whats going on, why this fix works at all, and test all features on all supported platforms.

I don't know when I will have the capacity for this.

Thanks for the review! I actually came up with the fix after doing some research on Yes Steve Model. It appears that they directly use these variables for playing hand swing animations. I hope this can provide a better understanding of the changes.

Is there a possibility to disable YSM body render?
Cuz when swinging with this mod, in FPV - I can see Models Body.

I've directly added this compatibility feature with Better Combat to YSM.
