Fix the bug of promote action not running when promote-pull-request was set to false.

https://github.com/SonarSource/sonar-dummy-js/actions/runs/17208109694/job/48813201106 - working as expected
I've decided to keep mise as public runners do not have jf installed and will cause the action to fail.

🤖 Pull Request summary

Refactors promotion logic to make PR promotion conditional based on input parameter.

• Removes conditional steps in GitHub Action and makes them always run
• Adds PROMOTE_PULL_REQUEST environment variable to control promotion behavior
• Updates promotion script to check flag and skip PR promotion when disabled
• Removes unused tools from mise configuration (gh, jq)
• Adds tests for new PR promotion toggle functionality

Review focus: Verify the logic change properly handles the promotion flow - ensure PRs are correctly skipped when the flag is false, and that removing the GitHub Action conditionals doesn't break existing workflows.
