fix: minSdkVersion being below that of the latest react native release

[GNUGradyn]

fixes #315

Thanks for this. Not sure it's completely necessary, as users could change their minimum app versions, but this may stop at least some of the build error tickets from showing up 🚀

[GNUGradyn]

They'd have to decrease it, which is not ideal

Note this is for the example app so it does nothing for end user projects.

I see that now... @GNUGradyn how did this PR help your situation? Were you using minSDKVersion in your project?

I've opened #324 to track a possible new fix.

I also see this: https://github.com/margelo/react-native-quick-crypto/blob/main/android/build.gradle#L107 which should "do the right thing" in the absence of any variables. Not sure why there was an issue unless we had variable name collision.

ah. looks like I updated this in the wrong file for my PR. defaultCOnfig.minSdkVersion in react-native-quick-crypto/android/build.gradle solves the issue. I guess this change was required for the example to work anyway lol. Will make PR for the actual correct file

Ah I see. That field is set when the library is compiled, Not sure why its set to 21 on npm. Something to do with the build environment maybe?
