Use Azul Zulu JDK8 distribution instead of Adoptium/OpenJDK on MacOS with Apple Silicon

[ap-kulkarni]

On MacOS with apple silicon, gradle check and gradle builds fail since adoptium/openjdk do not provide jdk 8 distributions for macos arm64 version. JDK8 is required in tasks modules:reindex:oldEs1Fixture and x-pack:qa:repository-old-versions. These changes will make use of the zulu distribution which provides a jdk8 version for macos arm64 and let the build tasks proceed successfully on Apple Silicon (M1/M2 processors) machines.
