New container builds are missing AI models

[LukeShortCloud]

Optional dependencies are not installed (which are all of the AI models).

Running python3.9 -m pip install .[all] addresses that. However, running that in the stage 2 container which does not have any compilers results in this error:

      CMake Error at CMakeLists.txt:5 (project):
        No CMAKE_CXX_COMPILER could be found.

Stage 1 compiles the binaries needed and then stage 2 copies those binaries over. That is expected behavior so you can ignore my last sentence from the previous comment. However, optional dependencies are still missing on new container image builds. My open PR is open to address that.
