ci: NPM publish package workflow should not be triggered if no tests are executed

[ppawlowski]

Currently, npm publish package workflow is triggered once the workflow with tests is complete and successful.
If introduced changes include documentation only, workflow with test is triggered but no tests are executed (expected). Unfortunately, in this scenario whole test workflow is considered as one which can trigger npm package publish workflow, due to the workflow_run: configuration.

The goal of this task is to refactor npm public package workflow and add a conditional which confirms that any of the test within Tests workflow completed with success.

Possible solution:

contains(github.event.workflow_run.jobs.*.name, 'Backend Tests') &&
contains(github.event.workflow_run.jobs.*.conclusion, 'success')
