Run GitHub workflows only when necessary for the change

We currently run GitHub workflows for all commits, we should be able to determine when running a particular workflow is not needed. For example changing the readme, should not trigger a release.
For this leveraging [paths](https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#using-filters-to-target-specific-paths-for-pull-request-or-push-events) filter is very helpful.
