As a user I dont see immediately why I cannot select a component if there already is one set

What versions of software are you using?

• Operating System: MacOS
• IntelliJ version: HEAD
• OpenShift version: Red Hat Sandbox

What did you run exactly?

Steps:

1. ASSERT: have a locally created component in your Red Hat sandbox
2. EXEC: pick "New Component" in the context menu of your project ("adietish-dev" in my case)
   
   

Result: In the upcoming dialog "Create component" the component types are all grayed out. At first sight one doesn't understand why. It's only after a 2nd closer look that one discovers the explanation on top of it: "Context already has a devfile, component type selection is not required"

Expected Result: The explanation should be stand out more, should be made more prominent so that I as a noob user gets it instantly why I cannot select a component type.
