CI config - Simplify the change patterns from 48 to 10
Context
We have a lot of change patterns: https://gitlab.com/gitlab-org/gitlab/-/blob/3968202bc77464df24edba9b0ce862ab363c22b5/.gitlab/ci/rules.gitlab-ci.yml#L167-636
Goal
In order to simplify the CI/CD config, the goal is to simplify the change patterns from 48 to 10.
Technical considerations
- We might need more data on how many pipelines were run based on a specific change pattern. Is there a way to know about this given an existing pipeline?
