Java version support requirements

[ivakoleva]

I noticed we do run tests in CI/CD using:

(32/49) Installing openjdk17-jre (17.0.6_p10-r0)
(33/49) Installing openjdk17-jmods (17.0.6_p10-r0)
(34/49) Installing openjdk17-jdk (17.0.6_p10-r0)

While our build requirements are specifically towards Java 11:

Java 11 and Docker are required.

I tried compiling with Java 11, our dependencies are too ahead of time. Also, we have a record keyword of >=14 introduced in #1787 in April. Therefore, at the moment, in fact we do not support Java 11 at all.

There are multiple mentions of Java 11+ requirement written, for example:
https://github.com/vmware/versatile-data-kit/blob/main/cicd/build.sh#L11

We need to sync our Java versions requirements understanding.

We support java 17+. The docs are out of date.
The reason we support java 17+ is that we want to be able to migrate to the latest spring eventually https://spring.io/blog/2022/05/24/preparing-for-spring-boot-3-0
