Add Lunar and other dynamic tags

Trying to see if we can use latest, rolling and devel to avoid needing a add a folder for new releases as soon as they are released.

We primarily use these images to build a package for a particular Linux distribution with fixed versions of libraries (fixed to a set of ABI compatible versions). Packages built on a rolling image will break at some moment in a future, because the rolling distro will be updated in a ABI incompatible way (it is natural for rolling distros).

Next, rolling images needs periodic updates and it is a manual work now. If we want to support them, we surely need some images build/push automation.

(Maybe we should drop fedora/rawhide and debian/sid, because dockerhub images are not updated for a long time and the presence of dockerfiles in the repository may be just confusing. Or actually update them periodically.)

I don't mind to make some effort in this direction, but I would start the discussion with your scenario.

As regarding interim Ubuntu releases (non-LTS), such as Ubuntu Lunar, I would skip them unless really necessary. They live short and mostly not worth effort of support packaging infra and packages for them.

I removed interim Ubuntu versions and Debian/Fedora rolling releases in #125.
