Podfile missing MinimumOSVersion

Upon submitting to the app store, I received the following error:

[logs] This might take a few minutes. Please don't interrupt the script.
[logs] [altool] 2024-01-28 18:45:33.968 *** Error: Asset validation failed Invalid Bundle. The bundle Balance.app/Frameworks/powersync-sqlite-core.framework does not support the minimum OS Version specified in the Info.plist. (ID: 0e66e9b9-a7e2-4cd8-a592-6c644f447519) (90208)

It looks like the build_pod.sh script could be updated with this change:
https://github.com/powersync-ja/powersync-sqlite-core/blob/main/build-pod.sh#L10-L29

 <key>MinimumOSVersion</key>
  <string>X.Y</string>

I believe CFBundleVersion and CFBundleShortVersionString also need to be added as well
