Stop eager presentation instantiation

From the inspection:

> Any of the constructors of AnAction with parameters instantiate the Presentation object. However, instantiating the Presentation object in constructor results in allocating resources, which may not be necessary. Instead of creating an instance of Presentation that stores text, description, or icon, it is more efficient to utilize no-argument constructors of AnAction and other base classes and follow the convention for setting the text, description, and icon in plugin.xml. The IDE will load text, description, and icon only when the action is actually displayed in the UI.

Confirmed that the label set in `plugin.xml` is sufficient:
