Switching GitHub Action to use Zulu Builds.

[carldea]

What this PR does / why we need it:

The AdoptOpenJDK has been discontinued since July 2021. When using Zulu you get all the latest updated (TCK Tested) builds for all versions of OpenJDK including archived builds (major fixed versions). Replacing the build distro to Zulu is nice because some environments use a major fixed version such as Java 8.0.192, that many vendor builds don't support.
This PR is backwards compatible since GitHub Actions setup-java@v1 originally used Azul Zulu.

Thank you. Glad to have helped contribute to this project.

@carldea Can you provide some links to show the fact that adopt has been discontinued?

Another thing to note (for good measure) is adding a major fixed release version such as Java 8.0.192. This is often a very good practice, when your software is used by vendors and/or customers relying on earlier releases (LTS fixed versions).
What's nice about this practice is the following example:

• Build/Test Java 8.0.192 passes (green)
• Build/Test Java 8 (latest) fails (red)

This indicates that it is not your code but the latest Java build that broke the build/test.

If you prefer, I will can create another PR to add Java 8.0.192 as an additional version to test.
I would use something like the following:

strategy:
      matrix:
        os: [ ubuntu-latest ]
        java-version: [ 8, 8.0.192 ]

谢谢你
