The zulujdk8 label does not work on Intel devices. The download variable returns a very old version of Zulu OpenJDK 8 (zulu8.9.0.4-ca-jdk8.0.60-macosx_x64.dmg).

Changing the downloadURL variable to this fixes the problem:
downloadURL=https://cdn.azul.com/zulu/bin/$(curl -fs "https://cdn.azul.com/zulu/bin/" | grep -Eio '">zulu8.*ca-jdk8.*x64.dmg(.*)' | cut -c3- | sed 's/<\/a><\/td>//' | sed -E 's/([0-9.]*)M//' | awk '{print $2 $1}' | sort -V | tail -1)

@drtaru can you please address or respond to @kryptonit1 's comment for zulujdk8 ?

More work needs to be done on this apparently. I don't have any bandwidth to work on or push a fix at the moment.

Closing due to open issues with no interest to fix
