[Resolver] Enable resolver test plugin tests (#81339) (#81906)

Resolver has a test plugin. It can be found in `x-pack/tests/plugin_functional`. You can try it out like this:
```
yarn start --plugin-path x-pack/test/plugin_functional/plugins/resolver_test/
```
This PR enables automated tests for the test plugin. This ensures that the test plugin will render.
