Remove calculate_images_to_build function

[SimonBaeumer]

Summary

Removing calculate_images_to_build function. This function was never used in the intended implementation. exclude was never used for pipeline.py in CI & scirpts, only include was used.
--include was only ever called once, it never used action=append. To simplify the implementation just the key of the image to build is returned.

Proof of Work

• CI Pipline
• rg search locally and check usages for --exclude and --include

❯ rg pipeline.py

I see the PR has been approved but all images builds are failing in CI
I'll block it to make sure we don't merge accidentally
