Document if ECA Access is required by ECA Enpoint

It seems to me ECA Endpoint submodule's events won't be triggered if there isn't a corresponding ECA Access event and "set access result" allow action

This is "almost" correct. What's required is that something declares the access permission for such a route. And the most common way is to do that with the Set access result action. However, that's not mandatory, there could be other means to implement the access control:

• Custom code
• Another action plugin, either custom or in a different contrib module

That's why we may not declare a hard dependency on eca_access, but documentation in the ECA Guide should address this.

I've added this to the documentation at https://ecaguide.org/plugins/eca/endpoint/events/eca_endpoint_response/
