Fix linting error

[DavidBertet]

• java.lang.Iterable#forEach requires minSdkVersion 24
• defaultConfig > targetSdkVersion 30 should be overridden by parent app, disable the error as it is Play Store specific

Summary

Issue raised by #566

Running the linter on example project

./example/android/gradlew lintDebug

raises 3 errors on the library itself

• java.lang.Iterable#forEach requires minSdkVersion 24
  • in rectBounds.forEach
  • in barcodes.forEach
• targetSdkVersion must be higher than 31 for the Google Play Store

Fix

• Bump minSdkVersion from 23 to 24
• Silent ExpiredTargetSdkVersion in the library because the parent app is setting their own. As it is a Google Play Store, someone using it on a private store would be fine
  • Is it needed to specify it at all on the library? Not sure

How did you test this change?

No more linting error. It shouldn't impact the project as minSdkVersion doesn't do much.
