Not all Zulu versions are available for Linux aarch64

[donbeave]

Hello!

I can not find Azul Zulu: 8.64.0.19 (8u345b01) version in asdf list-all java command on Linux ARM64 for the version which is available for that platform:
https://www.azul.com/downloads/?version=java-8-lts&architecture=arm-64-bit&package=jdk

And I found that this version is available in source JSON files which are used for generating index metadata files for macOS ARM, but not available to Linux ARM:

1. In this file you can find an object for macOS:

  },

2. But in this file you can not find any mention of zulu8.64.0.19-ca-jdk8.0.345-macosx_aarch64.tar.gz:
   https://joschi.github.io/java-metadata/metadata/ga/linux/aarch64.json

But can find other versions for this platform.

The reason why this particular version of the Azul Zulu build of OpenJDK is missing is because it is not listed on https://static.azul.com/zulu/bin/ which this project is using for a complete listing of available versions:

The regular non-musl builds for aarch64 on Linux are missing since at least Zulu build of OpenJDK 8.5.0.1-ca-jdk8.0.31. The last one which is available on https://static.azul.com/zulu/bin/ is zulu8.48.2.244-ca-jdk8.0.262-linux_aarch64.tar.gz which is also covered by this project: https://joschi.github.io/java-metadata/metadata/vendor/zulu/zulu8.48.2.244-ca-jdk8.0.262-linux_aarch64.tar.gz.json

@GeertjanWielenga Is this something you could kindly help with?

Are all Azul Zulu builds of OpenJDK supposed to end up on https://static.azul.com/zulu/bin/ as before?
