Tons of docker tags, little explanation

[pontus-mp]

Is your feature request related to a problem? Please describe. The documentation for the docker images points you at https://hub.docker.com/r/dunglas/frankenphp/tags, with... quite a few images (360+ pages worth at time of writing). Figuring out which ones are relevant for you can be a bit tricky, as tons of images has SHA-hashes in their names.

Describe the solution you'd like Adding some basic instructions for which image to pick would be great, basically something like what's available on https://hub.docker.com/_/php (under Image Variants). The pattern for packages that are relevant to users seem to be {FrankenPHPVersion}-php{Major.Minor}-{Distro}.
