Lets make "play" as action's default icon

[Paul-Bob]

Let's purge next_action since we're not using it anymore

@gabrielgiroe1 I let some comments for some last tweaks, otherwise the PR looks great, thank you! This is a cool improvement!

[adrianthedev]

Looks good! I haven't tested it.

I left one suggestions and one question.

GJ! I wanted this for such a long time!

[adrianthedev]

Do we need to specify a default here as well? Wouldn't the initializer default take precedence?

[gabrielgiroe1]

Yes, we must specify a default value. I tried as below and it won't get a default icon value.👇

define_method entity do |entity_class, arguments: {}, icon: nil|

[adrianthedev]

Also, let's see the docs.
Let's add the option as we have other options but also code examples on how users can do it in show_controls (and others) and in def actions.
