RADV variable in gaming.mdx deprecated/not-needed

With amdvlk being discontinued for some time and no longer available in the repositories is the variable in https://github.com/CachyOS/wiki/blob/next/src/content/docs/configuration/gaming.mdx#increase-maximum-shader-cache-size ( `AMD_VULKAN_ICD=RADV` ) necessary? Seems ripe for removal.
