Issue building on Windows

[Ty Fiero]

I'm using Tauri v2, Linux and Mac build just fine, but windows gives me the error below. I will create a PR to fix this, all that needs done is on lib.rs, line 41, change for window in &mut config.tauri.windows { to for window in &mut config.windows {, and line 91, change .join(&config.tauri.bundle.identifier) to .join(&config.identifier)

error[E0609]: no field tauri on type &mut tauri::Config
--> C:\Users\runneradmin/.cargo\registry\src\index.crates.io-6f17d22bba15001f\tauri-plugin-theme-0.4.0\src\lib.rs:41:31
