Only run cargo-test GH Action when wasm-lib is updated (#1718)

* Only run cargo-test GH Action when wasm-lib is updated
Because we don't care about src-tauri's Rust code in this action

* $APPDATA !== $APPCONFIG on Linux
+ change the bundle identifier back

* Undo that commit, wrong branch

* Change approach to ignore the Tauri Rust files instead

* Switch back to only check wasm-lib
