Make autofill case class arguments more visible

[tgodzik]

Describe the bug

I think this was actually reported multiple times that people wanted to use such a feature but weren't aware of it.

Currently it only shows up if you do write "auto...". Maybe we should show it more prominent or via code action so that it's easier to use.

I didn't realize this feature existed either. Typing "auto" is not an intuitive DX to me. Code action sounds right. It could also show up when invoking "Trigger Sugges" (or however it's called when pressing ctrl+space).
