Dropped support for Java 11, bump [email protected], [email protected]

[petruki]

This pull request updates the minimum supported Java version for the project from Java 11 to Java 17 and improves compatibility documentation. It also updates test dependencies, enhances Javadoc generation, and makes minor code improvements for null safety in test extension classes.

Java version and compatibility updates:

• Updated Java version requirement from 11 to 17 in pom.xml, GitHub Actions workflows (master-2.yml, release.yml), and documentation. The build and release pipelines now only test against Java 17, 21, and 25, and the Maven Central release step uses Java 17. [1] [2] [3] [4]
• Improved documentation in README.md to clarify SDK compatibility: v1.x requires Java 8+ (non-Jakarta EE 9), v2.x requires Java 17+ (Jakarta EE 9+).

Dependency and plugin updates:

• Upgraded test dependencies: okhttp to 5.2.0, junit-jupiter and junit-platform-launcher to 6.0.0 in pom.xml.
• Enhanced Maven Javadoc plugin configuration to enable stricter doclint checks and suppress missing documentation warnings.
