[ENH] Docker image for aeon with Numba caching

[SebastianSchmidl]

Describe the feature or idea you want to propose

Aeon should provide a Dockerfile or Docker image that showcases how to install and run aeon within Docker.
Additionally, aeon uses a lot of Numba-JITed code that gets compiled on first usage. This means that when using Docker, the functions are getting recompiled every time the Docker container is restarted. @chrisholder implemented caching for the Numba-compiled code in our CI. We should support similar caching for Docker images.

Describe your proposed solution

• Create example Dockerfiles (simple and with Numba-caching)
• Build and publish Docker images to the GitHub registry (ghcr.io/aeon-toolkit/aeon) for every release with GitHub Actions (CI)
• Document usage

Describe alternatives you've considered, if relevant

Just document the problem with Docker-Numba-caching and how to solve it in our documentation.
