We're introducing a rocky10 flavor of Dockerfile to provide migrid in Rocky10 containers (#135).
With Rocky10 and some of the dependencies we rely on changing it requires some work and testing to stabilize the set up.

With Rocky9 still maintained for long it's not urgent but we want to have it ready before EoL of the 9.x series.

Our migrid sites have been thoroughly tested with Python 3.9 on Rocky9, so they should just run on the newer Python 3.12 but we need more testing.
