* Remove accidental string interpolation from action.yml

* Fix test workflow filters

* Improve self-test

* Add test case for matching any changed file

* Fix workflow test - step `name` was used instead of `id`

* Extend default pull_request trigger types

* Remove `edited` trigger to avoid executing workflow on non-code changes
