As for the question, Docker can’t fix if a script uses http instead of https. I would try to find a forward poxy that can change all http requests to be https. I found this in ServerFault, but I would recommend you to try to look for more solutions and find references in official documentations.
If you can’t or don’t want to run a proxy outside of your CI/CD pipeline, I think you could run it as a container as a part of your pipeline and use build arguments to set the proxy for the build.
