Do not allow subscribing to Base channel 
Closes #40482

Prior to this commit it was possible to subscribe with
`ActionCable::Channel::Base` as the subscription class. While it doesn't
seem possible to exploit this in away way, it also doesn't seem like
something we need to allow.

This commit swaps [Module#>=][gte] with [Module#>][gt] to prevent
subscribing to a channel when `ActionCable::Channel::Base` is the
subscription class.

Action Cable – Integrated WebSockets for Rails

Action Cable seamlessly integrates WebSockets with the rest of your Rails application. It allows for real-time features to be written in Ruby in the same style and form as the rest of your Rails application, while still being performant and scalable. It's a full-stack offering that provides both a client-side JavaScript framework and a server-side Ruby framework. You have access to your full domain model written with Active Record or your ORM of choice.

You can read more about Action Cable in the Action Cable Overview guide.
