[bug] bundler doesn't clean up `.app` bundle if only `.dmg` is enabled

[tauri-bot]

This issue has been upstreamed from tauri-apps/tauri-action#476

Is it possible to consider adding a variable Bundles like pnpm tauri build --help

Sometimes I only want to upload MSI and DMG bundles, but currently it will upload all the bundles, include app and exe.

  -b, --bundles [<BUNDLES>...]
          Space or comma separated list of bundles to package.
          
          Each bundle must be one of `deb`, `appimage`, `msi`, `app` or `dmg` on MacOS and `updater` on all platforms. If `none` is specified, the bundler will be skipped.
          
          Note that the `updater` bundle is not automatically added so you must specify it if the updater is enabled.
