"windows" not "win32" for Windows in os.platform() possible values

[boan-anbo]

It's windows not win32 as in the doc.

tauri/tooling/api/src/os.ts

Line 38 in 40d08a6

* The value is set at compile time. Possible values are `'aix'`, `'darwin'`, `'freebsd'`, `'linux'`, `'openbsd'`, `'sunos'`, and `'win32'`.

Thanks for catching this, PR'd a fix now, it will return win32 as stated in the docs.
