AWS SDK V1 for Java no longer released

EOL was end of 2025, apparently.

We need to look at migration to SDK V2.

discovery-aws-api module still depends on the legacy com.amazonaws (SDK v1) for both EC2 and ECS discovery, while discovery-aws-api-async already uses SDK V2.

@mdedetrich @raboof @He-Pin @nvollmar should we just deprecate discovery-aws-api module and encourage users to switch to the async lib?

Basically rewrite the docs to say the async lib is the one to use and that is not preview any more. https://pekko.apache.org/docs/pekko-management/current/discovery/aws.html
