Add support for Amazon Linux 2023

[dabbeg]

Amazon has released a new distribution AL2023.

https://aws.amazon.com/about-aws/whats-new/2023/03/amazon-linux-2023/

I am testing it out and I see that Adoptium installer only supports AL2.

@dabbeg Can you send the error message you're seeing?

Hey @karianna, here are the steps I go through.

This new AL2023 has the $releasever is 2023.0.20230419 and it is unable to find it in the package registry https://packages.adoptium.net/ui/native/rpm/amazonlinux/ which seems to support only version 2 for amazonlinux.

If you replace \$releasever with 2 it should still install and work ok, but it's something we should definitely look it. Thanks for raising this.

In the meantime if you try that and hit any problems, let us know as we're not currently performing any testing on AL2023

[tellison]

This issue was discussed at the Adoptium Project Management Committee meeting on April 26th.

We noted that Amazon Linux is not an officially supported distribution for use of Temurin, but we are are thankful that you are testing here and are interested in any findings, good or bad.

We also considered that it may be confusing if we enabled/described the install instructions for Temurin on that platform without it having undergone full testing at the project. Therefore we will aim to provision an Amazon Linux machine in our testing matrix to ensure things behave as expected there, and this may enable it to become a best-effort supported platform in future.

The list of project supported platforms and distributions is available on the Adoptium website.
