WIP: 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 set for pipeline.py, 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
