gcc-12 doesn't work in container

[derickson2402]

some sort of bug is happening when using scl enable from inside a wrapper script, so gcc-12 doesnt work due to linker errors.

current fix is to use a different container tag dockerized-caen:gcc12 which has gcc-12.2.1 enabled and set as default.

down the road, would be best to just have different tags for the different programs in the container and have a seperate base image rather than trying to do 1 container that is identical to caen. fixes this issue, makes more sense as a container infrastructure, and also wayyyy decreases the image size
