Remove these since 1) they are not part of the hash and 2) are already cached in the cache-cargo action before this one.

Nothing obvious that stands out. All the newly added files all exist on disk so I think it's a publish and see situation.

Closes #13133
This PR adds an a new Oxide target for
wasm32-wasip1-threads:@tailwindcss/oxide-wasm32-wasi. The goal of this is to enable more environments to run Oxide, including (but not limited to) StackBlitz.We're making use of
napi-rs's upcoming v3 features to simplify the setup here, meaningnapi-rswill configure the WASM target and create an npm package that works across Node and browser environments.MacOS AArch64 issues
While setting up an integration test for the new WASM target, I ran into an issue where FS reads where not terminating on macOS. After some research I found this to be a limitation of the Node.js container interface right now, see: nodejs/node#47193
Windows issues
We also found that the Node.js wasi container does not properly support Windows: nodejs/uvwasi#11
For now we, it's probably best for MacOS AArch64 users and Windows users to use the native modules instead.
Test plan
The
@tailwindcss/oxide-wasm32-wasinpm package can be built locally viapnpm buildand then run with the Oxide API. A usage example can be taken from the newly added integration test.Furthermore this was tested to work as a polyfill on StackBlitz: https://stackblitz.com/edit/vitejs-vite-uks3gt5p
