chore: narrow CI workflow trigger scope for Zephyr compilation

Optimize GitHub Actions workflow execution by limiting triggers to only
changes in the compilation_on_zephyr.yml workflow file itself, reducing
unnecessary workflow runs when other .github files are modified.
* Update pull_request trigger paths to target specific workflow file
* Update push trigger paths to target specific workflow file
* Eliminates redundant CI runs for documentation and script changes
