Optimize CI jobs to run only necessary tasks

[otegami]

What is your problem?

Current Situation

Our CI pipeline runs all tasks for every change, which can lead to unnecessary resource consumption and stop the following tasks.

What we expected

To improve the efficiency of our CI pipeline, we want to optimize our jobs to execute only the necessary tasks based on the changes made.

• e.x.
  • We trigger documentation generation jobs only for document changes

We trigger documentation generation jobs only for document changes

This is a missing optimization.
