no-unreachable-types: Interface implementing other interfaces are always unreachable

Describe the bug

If you have one interface SUB that implements another interface PARENT, then the interface SUB and all types implementing this interface are marked as unreachable - although PARENT is used and is correctly not marked as unreachable.

To Reproduce Steps to reproduce the behavior:

interface User {
  id: ID!
}

interface Manager implements User {
  id: ID!
}

type TopManager implements Manager {
  id: ID!
  name: String
}

type Query {
  me: User
}

Manager and TopManager are marked as unreachable, although they are reachable by Query > me.

Expected behavior

No error.

Environment:

• OS:
• @graphql-eslint/...: 1.1.4
• NodeJS:
