fix: exports in Desktop builds

The way a Tauri app checks for the running environment has changed
between the Tauri versions 1 and 2. In the previous 2.0 builds, this was
not updated causing the regression of exports not working. This commit
checks the correct value - window.__TAURI_INTERNALS__ to fix that issue.
