Set Java source/target compatibility for react-native-gradle-plugin to 8

cortinico · Andrei Shikov · commit f5d371a2f994 · 2022-02-24T14:35:00.000Z
Summary:
This is necessary otherwise when building from source on JVM &lt; 11, the `compileJava`
task of the Gradle Plugin will fail with `invalid source: 11`.
Essentially the Gradle build will not even start because of this. Instead we delegate
to a better formatted warning from either AGP or from our plugin.

Changelog:
[Internal] [Changed] - Set Java source/target compatibility for react-native-gradle-plugin to 8
