Action `firebase_app_distribution_get_latest_release` considers `createTime` instead of `buildVersion`

### Issue Description
`firebase_app_distribution_get_latest_release` implements `list_project_app_releases` from Google API's `FirebaseappdistributionV1`, passing page size 1, as shown on the snippet below:

https://github.com/firebase/fastlane-plugin-firebase_app_distribution/blob/bdc1358767af1063962a56e04e09a7b4c4c1eafd/lib/fastlane/plugin/firebase_app_distribution/actions/firebase_app_distribution_get_latest_release.rb#L17-L34

This by default returns the latest release by `createTime`. However, considering the context of mobile app releases versioning standards, the `buildVersion` parameter would be more consistent to determine which release is in fact the latest (build version number for a new release should always be greater than the previous, as enforced by public app stores - Google Play, App Store).

My suggestion is to either change this implementation to consider buildVersion as parameter to find the most recent release, or add an optional parameter to `firebase_app_distribution_get_latest_release`, so the developer can select which parameter to use.
