[Documentation] templateOnly appears in the wrong area, under Controller methods

[pzuraq]

📙 Describe the Issue

templateOnly is importable from @ember/component/template-only according to the documentation, but it shows up in the API docs for Controller as a method.

🔬 Minimal Reproduction

https://api.emberjs.com/ember/3.23/classes/Controller/methods/templateOnly?anchor=templateOnly

😕 Actual Behavior

Appears in the Controller API docs

🤔 Expected Behavior

Should appear as a submodule of @ember/component

I think I figured out what causes this. The templateOnly doc comment describes a @method but the @ember/component/template-only module doesn't define a class. By default YUIDoc seems to link methods to the class that was last parsed (and in this case that seems to be the Controller class).

From the YUIDoc syntax reference:

@method Indicates that the block describes a method for the current class. By default, the "current" class is the last class that YUIDoc parsed, but you can reset this with the @for tag.

So the fix would be to add a @for to the doc comment. Itt seems that other exports are documented that way as well. For example the runloop exports.
