Shorebird OTA Patches for Mac App Store Apps

Use this workaround to patch a Flutter macOS app distributed through the Mac App Store before Shorebird has first-class Mac App Store support.

The workaround starts after your Mac App Store app is live. Build, sign, submit, review, approve, and release the app exactly the way you already do.

Shorebird needs to generate the patch from the same .app bundle your users have installed. For Mac App Store apps, that is the store-delivered .app, not the .app on your build machine. After the app is live, the script's register-baseline command downloads the store-delivered app and uploads that bundle to Shorebird as the baseline for future patches.

Upstream issue: shorebirdtech/shorebird#3223.
