Update docker native libs container (elastic#138227)

This commit has a few small fixes for the DockerFiles used to build the simdvec library:

1. ERROR - Replace openjdk-17-jdk with openjdk-21-jdk - some distros have dropped 17. This is just the jdk that runs Gradle.
2. WARNING - Use apt-get to avoid WARNING : apt does not have a stable CLI interface. Use with caution in scripts.
3. WARNING - Fix for warning - JSON arguments recommended for ENTRYPOINT/CMD to prevent unintended behavior related to OS signals
4. Update the gradle wrapper
