Docker scripts no longer work due to outdated CMake in ubuntu Bionic

[ErikTempelaarVO]

The scripts to build the docker image(s) fail because of ubuntu:bionic, this comes with CMake 3.10.2 and the project requires at least 3.16.

~/cyclonedds/scripts/docker$ docker run -it --rm ubuntu:cyclonedds bash
root@caed9758c075:/# cmake --version
cmake version 3.10.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Changing scripts/docker/Dockerfile to build FROM ubuntu:jammy works.
Happy to provide a PR, if needed.
