There's a merged pull request on the void-packages repository

Update Vulkan to v1.2.135
https://github.com/void-linux/void-packages/pull/20243

Description:
It hasn't been updated on Void since December, and newer games may expect later Vulkan versions.  
I'm still very new both to pull requesting in general and to xbps packaging, so please let me know if there's something I totally missed.
