Awesome stuff man, this makes the pipeline sooo much shorter :nerdsnipe:

going to trust that you know what you're doing with these changes, cause I've never touched python installs this far into the weeds ;)

Also, the base1, base2, and base3 images were only introduced to split up the build because it took over 6 hours which is the timeout for GH actions, so we can remove them and combine them back into one base image build now

Yeah for sure this is a good way of installing python, I've used it before in production successfully.

Agreed. I want to make sure it's stable and then in a follow up MR we can remove the splits.
