add webgpu.yml on release

[ygdrasil-io]

Hello! I've started using the webgpu.yml to regenerate my Kotlin bindings, and it's definitely more convenient than working directly with the C headers. I was wondering if the community would be open to including this YAML file alongside the headers in each release ?

Makes sense to me! This line moves the webgpu.h into the archive, so adding a line there for the yml file should do the trick.
